application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee an
Officer's Certificate stating that all conditions precedent, if any, provided
for in this Indenture (including any covenant compliance with which constitutes
a condition precedent) relating to the proposed action have been complied with
and an Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this

                                       11

<PAGE>

Indenture relating to such particular application or request, no additional
certificate or opinion need be furnished.

Every certificate or opinion with respect to compliance with a covenant or
condition provided for in this Indenture (other than pursuant to Section 1004)
shall include:

            (1)   a statement that each individual signing such certificate or
      opinion has read such covenant or condition and the definitions herein
      relating thereto;

            (2)   a brief statement as to the nature and scope of the
      examination or investigation upon which the statements or opinions
      contained in such certificate or opinion are based;

            (3)   a statement that, in the opinion of each such individual, he
      has made such examination or investigation as is necessary to enable him

            (4)   a statement as to whether, in the opinion of each such
      individual, such covenant or condition has been complied with.

            SECTION 103. Form of Documents Delivered to Trustee. In any case
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered by the opinion of, only one such Person, or that they be so
certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons
as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

            Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

            Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

            SECTION 104. Acts of Holders. Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of the Outstanding Securities of all series or one
or more series, as the case may be, may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Holders in person
or by agents duly appointed in writing. If Securities of a series are

                                       12

<PAGE>

issuable as Bearer Securities, any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this Indenture to be given
or taken by Holders of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company. Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Company, if made in the manner provided in this Section. The
record of any meeting of Holders of Securities shall be proved in the manner
provided in Section 1506.

            (a)   The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

            (b)   The principal amount and serial numbers of Registered
Securities held by any Person, and the date of holding the same, shall be proved
by the Security Register.

            (c)   The principal amount and serial numbers of Bearer Securities
held by any Person, and the date of holding the same, may be proved by the
production of such Bearer Securities or by a certificate executed, as
depositary, by any trust company, bank, banker or other depositary, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned such Person had on deposit with such
depositary, or exhibited to it, the Bearer Securities therein described; or such
facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to
be satisfactory. The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner that the Trustee deems
sufficient.

            (d)   If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company

                                       13

<PAGE>

may, at its option, by or pursuant to a Board Resolution, fix in advance a
record date for the determination of Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. Notwithstanding TIA Section 316(c),
such record date shall be the record date specified in or pursuant to such Board
Resolution, which shall be a date not earlier than the date 30 days prior to the
first solicitation of Holders generally in connection therewith and not later
than the date such solicitation is completed. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

            (e)   Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefore or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made
upon such Security.

            SECTION 105. Notices, etc. to Trustee and Company. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other documents provided or permitted by this Indenture to be made upon, given
or furnished to, or filed with,

            (1)   the Trustee by any Holder or by the Company shall be
      sufficient for every purpose hereunder if made, given, furnished or filed
      in writing to or with the Trustee at its Corporate Trust Office,
      ATTENTION: INSTITUTIONAL TRUST SERVICES, or

            (2)   the Company by the Trustee or by any Holder shall be
      sufficient for every purpose hereunder (unless otherwise herein expressly
      provided) if in writing and mailed, first-class postage prepaid or by
      overnight delivery service, to the Company addressed to it at the address
      of its principal office specified in the first paragraph of this Indenture
      or at any other address previously furnished in writing to the Trustee by
      the Company.

            SECTION 106. Notice to Holders; Waiver. Where this Indenture
provides for notice of any event to Holders of Registered Securities by the
Company or the Trustee, such notice shall be sufficiently given (unless
otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to each such Holder affected by such event, at his address as
it appears in the Security Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice. In any
case where notice to Holders of Registered Securities is given by mail, neither
the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities

                                       14

<PAGE>

given as provided. Any notice mailed to a Holder in the manner herein prescribed
shall be conclusively deemed to have been received by such Holder, whether or
not such Holder actually receives such notice.

            In case, by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause, it shall be impractical to mail
notice of any event to Holders of Registered Securities when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to the Trustee shall be
deemed to be sufficient giving of such notice for every purpose hereunder.

            Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given to Holders of Bearer Securities if published in an
Authorized Newspaper in The City of New York and in such other city or cities as
may be specified in such Securities on a Business Day at least twice, the first
such publication to be not earlier than the earliest date, and not later than
the latest date, prescribed for the giving of such notice. Any such notice shall
be deemed to have been given on the date of the first such publication.

            In case, by reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause,
it shall be impracticable to publish any notice to Holders of Bearer Securities
as provided above, then such notification to Holders of Bearer Securities as
shall be given with the approval of the Trustee shall constitute sufficient
notice to such Holders for every purpose hereunder. Neither the failure to give
notice by publication to Holders of Bearer Securities as provided above, nor any
defect in any notice so published, shall affect the sufficiency of such notice
with respect to other Holders of Bearer Securities or the sufficiency of any
notice to Holders of Registered Securities given as provided herein.

            Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

            Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

            SECTION 107. Effect of Headings and Table of Contents. The Article
and Section headings herein and the Table of Contents are for convenience only
and shall not affect the construction hereof.

            SECTION 108. Successors and Assigns. All covenants and agreements in
this Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

                                       15

<PAGE>

            SECTION 109. Separability Clause. In case any provision in this
Indenture or in any Security or coupon shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

            SECTION 110. Benefits of Indenture. Nothing in this Indenture or in
the Securities or coupons, express or implied, shall give to any Person, other
than the parties hereto, any Authenticating Agent, any Paying Agent, any
Securities Registrar and their successors hereunder and the Holders of
Securities or coupons, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

            SECTION 111. Governing Law. THIS INDENTURE AND THE SECURITIES AND
COUPONS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE
STATE OF NEW YORK. THIS INDENTURE IS SUBJECT TO THE PROVISIONS OF THE TRUST
INDENTURE ACT THAT ARE REQUIRED TO BE PART OF THIS INDENTURE AND SHALL, TO THE
EXTENT APPLICABLE, BE GOVERNED BY SUCH PROVISIONS.

            SECTION 112. Legal Holidays. In any case where any Interest Payment
Date, Redemption Date, sinking fund payment date or Stated Maturity or Maturity
of any Security shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or of any Security or
coupon other than a provision in the Securities of any series which specifically
states that such provision shall apply in lieu of this Section), payment of
principal (or premium, if any) or interest, if any, need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date or sinking fund payment date, or at the
Stated Maturity or Maturity; provided that no interest shall accrue for the
period from and after such Interest Payment Date, Redemption Date, sinking fund
payment date, Stated Maturity or Maturity, as the case may be.

            SECTION 113. No Recourse. No recourse for the payment of the
principal of or premium, if any, or interest on any Security or any coupons
appertaining thereto, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in this Indenture or in any supplemental indenture, or in any
Security or any coupons appertaining thereto, or because of the creation of any
indebtedness represented thereby, shall be had against any director, officer,
employee, or stockholder as such, past, present or future, of the Company or any
of its Affiliates or any successor Person of the Company, either directly or
through the Company or any of its Affiliates or any successor Person of the
Company, whether by virtue of any constitution, statute or rule of law, or by
the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issue of the Securities.

                                 SECURITY FORMS

            SECTION 201. Forms Generally. The Registered Securities, if any, of
each series and the Bearer Securities, if any, of each series and related
coupons shall be in substantially the forms as shall be established by, or
pursuant to a Board Resolution or, subject to Section 303, set forth in, or
determined in the manner provided in, an Officer's Certificate pursuant to a
Board Resolution, or in one or more indentures supplemental hereto, in each case
with such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by this Indenture, and may have such letters,
numbers or other marks of identification and such legends or endorsements placed
thereon as may be required to comply with the rules of any securities exchange
or as may, consistently herewith, be determined by the officers executing such
Securities or coupons, as evidenced by their execution of the Securities or
coupons. If the forms of Securities or coupons of any series are established by
action taken pursuant to a Board Resolution, a copy of an appropriate record of
such action shall be certified by the Secretary or Assistant Secretary of the
Company, and delivered to the Trustee at or prior to the delivery of the Company
Order contemplated by Section 303 for the authentication and delivery of such
Securities or coupons. Any portion of the text of any Security may be set forth
on the reverse thereof, with an appropriate reference thereto on the face of the
Security.

            Unless otherwise specified as contemplated by Section 301,
Securities in bearer form shall have interest coupons attached.

            The Trustee's certificate of authentication on all Securities shall
be in substantially the form set forth in this Article.

            The definitive Securities and coupons shall be printed, lithographed
or engraved on steel-engraved borders or may be produced in any other manner,
all as determined by the officers of the Company executing such Securities, as
evidenced by their execution of such Securities or coupons.

            SECTION 202. Form of Trustee's Certificate of Authentication.
Subject to Section 611, the Trustee's certificate of authentication shall be in
substantially the following form:

                     TRUSTEE'S CERTIFICATE OF AUTHENTICATION

            Dated: ____________________

            This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

                                       JPMORGAN CHASE BANK,
                                         as Trustee

            SECTION 203. Securities Issuable in Global Form. If Securities of or
within a series are issuable in global form, as specified as contemplated by
Section 301, then, notwithstanding clause (8) of Section 301, any such Security
shall represent such of the Outstanding Securities of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of Outstanding Securities of such series from time to time endorsed thereon and
that the aggregate amount of Outstanding Securities of such series represented
thereby may from time to time be increased or decreased to reflect exchanges.
Any endorsement of a Security in global form to reflect the amount, or any
increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made by the Trustee in such manner and upon instructions given
by such Person or Persons as shall be specified therein or in the Company Order
to be delivered to the Trustee pursuant to Section 303 or Section 304. Subject
to the provisions of Section 303 and, if applicable, Section 304, the Trustee
shall deliver and redeliver any Security in permanent global form in the manner
and upon instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 303 or Section
304 has been, or simultaneously is, delivered, any instructions by the Company
with respect to endorsement or delivery or redelivery of a Security in global
form shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

            The provisions of the last sentence of Section 303 shall apply to
any Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

            Notwithstanding any provisions of Section 307 to the contrary,
unless otherwise specified as contemplated by Section 301, payment of principal
of (and premium, if any) and interest, if any, on any Security in permanent
global form shall be made to the Person or Persons specified therein.

            Notwithstanding the provisions of Section 309 and except as provided
in the preceding paragraph, the Company, the Trustee and any agent of the
Company and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a permanent
global Security in bearer form, Euroclear or Clearstream.

      1305);

      calculated if other than on the basis of a 360-day year of twelve 30-day
      months;

            (5)   the place or places, if any, other than or in addition to the
      Borough of Manhattan, The City of New York, where the principal of (and
      premium, if any) and interest, if any, on Securities of the series shall

      denominations of $5,000, the denomination or denominations in which any
      Bearer Securities of the series shall be issuable;

            (9)   if other than the Trustee, the identity of each Security
      Registrar and/or Paying Agent;

            (10)  if other than the principal amount thereof, the portion of the
      principal amount of Securities of the series that shall be payable upon
      declaration of acceleration of the Maturity thereof pursuant to Section
      502 or the method by which such portion shall be determined;

            (11)  if other than Dollars, the Currency in which payment of the
      principal of (or premium, if any) or interest, if any, on the Securities
      of the series shall be payable or in which the Securities of the series
      shall be denominated and the particular provisions applicable thereto in
      accordance with, in addition to or in lieu of any of the provisions of
      Section 312;

            (12)  whether the amount of payments of principal of (or premium, if
      any) or interest, if any, on the Securities of the series may be
      determined with reference to an index, formula or other method (which
      index, formula or method may be based, without limitation, on one or more
      Currencies, commodities, equity indices or other indices), and the manner
      in which such amounts shall be determined;

            (13)  whether the principal of (or premium, if any) or interest, if
      any, on the Securities of the series are to be payable, at the election of
      the Company or a Holder thereof, in a Currency other than that in which
      such Securities are denominated or stated to be payable, the period or
      periods within which (including the Election Date), and the terms and
      conditions upon which, such election may be made, and the time and manner
      of determining the exchange rate between the Currency in which such
      Securities are denominated or stated to be payable and the Currency in

      any of the provisions of Section 312;

            (14)  the designation of the initial Exchange Rate Agent, if any, or
      any depositaries;

            (15)  the applicability, if any, of Sections 1402 and/or 1403 to the
      Securities of the series and any provisions in modification of, in
      addition to or in lieu of any of the provisions of Article Fourteen that
      shall be applicable to the Securities of the series;

      Securities of the series upon the occurrence of such events as may be
      specified;

            (17)  any deletions from, modifications of or additions to the
      Events of Default or covenants of the Company with respect to Securities
      of the series, whether or not such Events of Default or covenants are
      consistent with the Events of Default or covenants set forth herein;

            (18)  whether Securities of the series are to be issuable as
      Registered Securities, Bearer Securities (with or without coupons) or
      both, any restrictions applicable to the offer, sale or delivery of Bearer
      Securities, whether such Securities of any series are to be issuable
      initially in temporary global form and whether any Securities of the
      series are to be issuable in permanent global form with or without coupons
      and, if so, whether beneficial owners of interests in any such permanent
      global Security may exchange such interests for Securities of such series
      and of like tenor of any authorized form and denomination and the
      circumstances under which any such exchanges may occur, if other than in
      the manner provided in Section 305, whether Registered Securities of the
      series may be exchanged for Bearer Securities of the series (if permitted
      by applicable laws and regulations), and the circumstances under which and
      the place or places where any such exchanges may be made and if Securities
      of the series are to be issuable in global form, the identity and any
      temporary global security representing Outstanding Securities of any
      initial depository therefor;

            (19)  the date as of which any Bearer Securities of the series and
      any temporary global security representing Outstanding Securities shall be
      dated if other than the date of original issuance of the first Security of
      the series to be issued;

            (20)  the Person to whom any interest on any Registered Security of
      the series shall be payable, if other than the Person in whose name that
      Security (or one or more Predecessor Securities) is registered at the
      close of business on the Regular Record Date for such interest, the manner
      in which, or the Person to whom, any interest on any Bearer Security of
      the series shall be payable, if otherwise than upon presentation and
      surrender of the coupons appertaining thereto as they severally mature,
      and the extent to which, or the manner in which, any interest payable on a

      other than in the manner provided in Section 304;

            (21)  if Securities of the series are to be issuable in definitive
      form (whether upon original issue or upon exchange of a temporary Security
      of such series) only upon

                                       21

<PAGE>

      receipt of certain certificates or other documents or satisfaction of
      other conditions, the form and/or terms of such certificates, documents or
      conditions;

            (22)  if the Securities of the series are to be issued upon the
      exercise of warrants, the time, manner and place for such Securities to be
      authenticated and delivered;

            (23)  whether, under what circumstances and the Currency in which
      the Company will pay Additional Amounts as contemplated by Section 1005 on
      the Securities of the series to any Holder who is not a United States
      person (including any modification to the definition of such term) in
      respect of any tax, assessment or governmental charge and, if so, whether
      the Company will have the option to redeem such Securities rather than pay
      such Additional Amounts (and the terms of any such option);

            (24)  if the Securities of the series are to be convertible into or
      exchangeable for any securities of any Person (including the Company), the
      terms and conditions upon which such Securities will be so convertible or
      exchangeable;

            (25)  whether the Securities of such series are subject to
      subordination and the terms of such subordination; and

            (26)  any other terms, conditions, rights and preferences (or
      limitations on such rights and preferences) relating to the series (which
      terms shall not be inconsistent with the requirements of the Trust
      Indenture Act or the provisions of this Indenture).

            All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution or pursuant to authority
granted by one or more Board Resolutions (subject to Section 303) and set forth
in such Officer's Certificate or in any such indenture supplemental hereto. Not
all Securities of any one series need be issued at the same time, and, unless
otherwise provided, a series may be reopened for issuances of additional
Securities of such series.

            If any of the terms of the series are established by action taken
pursuant to one or more Board Resolutions or pursuant to authority granted by
one or more Board Resolutions, such Board Resolutions shall be delivered to the
Trustee at or prior to the issuance of the first Security of such series.

            SECTION 302. Denominations. The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301. With respect to Securities of any series denominated in Dollars, in the
absence of any such provisions, the Registered Securities of such series, other
than Registered Securities issued in global form (which may be of any
denomination), shall be issuable in denominations of $1,000 and any integral
multiple thereof and the Bearer Securities of such series, other than the Bearer
Securities issued in global form (which may be of any denomination), shall be
issuable in the denomination of $5,000.

                                       22

<PAGE>

            SECTION 303. Execution, Authentication, Delivery and Dating. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Company by its Chairman, its President or a Vice President, under its
corporate seal affixed thereto or reproduced thereon attested by its Secretary
or an Assistant Secretary. The signature of any of these officers on the
Securities or coupons may be the manual or facsimile signatures of the present
or any future such authorized officer and may be imprinted or otherwise
reproduced on the Securities.

            Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

            At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any series together
with any coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with such Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate in the form set forth in Exhibit A-1
to this Indenture, dated no earlier than 15 days prior to the earlier of the
date on which such Bearer Security is delivered and the date on which any
temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture. If any
Security shall be represented by a permanent global Bearer Security, then, for
purposes of this Section and Section 304, the notation of a beneficial owner's
interest therein upon original issuance of such Security or upon exchange of a
portion of a temporary global Security shall be deemed to be delivery in
connection with its original issuance of such beneficial owner's interest in
such permanent global Security. Except as permitted by Section 306, the Trustee
shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and cancelled. If not all
the Securities of any series are to be issued at one time and if the Board
Resolution, Officer's Certificate pursuant to a Board Resolution, or
supplemental indenture establishing such series shall so permit, such Company
Order may set forth procedures acceptable to the Trustee for the issuance of
such Securities and determining terms of particular Securities of such series
such as interest rate, stated maturity, date of issuance and date from which
interest shall accrue.

            In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Opinion of Counsel stating in effect (subject to customary exceptions):

            (a)   that the form or forms of such Securities and any coupons have
      been established in conformity with the provisions of this Indenture;

                                       23

<PAGE>

            (b)   that the terms of such Securities and any coupons have been
      established in conformity with the provisions of this Indenture;

            (c)   that such Securities, together with any coupons appertaining
      thereto, when completed by appropriate insertions and executed and
      delivered by the Company to the Trustee for authentication in accordance
      with this Indenture, authenticated and delivered by the Trustee in
      accordance with this Indenture and issued by the Company in the manner and
      subject to any conditions specified in such Opinion of Counsel, will be
      the legal, valid and binding obligations of the Company, enforceable
      against the Company in accordance with their terms, subject to the effect
      of any applicable bankruptcy, insolvency, reorganization, moratorium and
      other similar laws affecting creditors' rights generally (including
      without limitation on all laws relating to fraudulent transfers), to
      general principles of equity;

            (d)   that all laws and requirements in respect of the execution and
      delivery by the Company of such Securities, any coupons and of the
      supplemental indentures, if any, have been complied with and that
      authentication and delivery of such Securities and any coupons and the
      execution and delivery of the supplemental indenture, if any, by the
      Trustee will not violate the terms of the Indenture;

            (e)   that the Company has the corporate power to issue such
      Securities and any coupons, and has duly taken all necessary corporate
      action with respect to such issuance; and

            (f)   that the issuance of such Securities and any coupons will not
      contravene the articles of incorporation or by-laws of the Company or
      result in any violation of any of the terms or provisions of any law or
      regulation or of any indenture, mortgage or other agreement known to such
      Counsel by which the Company is bound.

            Notwithstanding the provisions of Section 301 and of the preceding
two paragraphs, if not all the Securities of any series are to be issued at one
time, it shall not be necessary to deliver the Officer's Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to the preceding two paragraphs prior to or at the
time of issuance of each Security, but such documents shall be delivered prior
to or at the time of issuance of the first Security of such series.

            The Trustee shall not be required to authenticate and deliver any
such Securities if the issue of such Securities pursuant to this Indenture will
affect the Trustee's own rights, duties or immunities under the Securities and
this Indenture or otherwise in a manner which is not reasonably acceptable to
the Trustee.

            Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date specified
as contemplated by Section 301.

            No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized
officer, and such certificate upon any Security shall be

                                       24

<PAGE>

conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder and is entitled to the benefits of this
Indenture.

            Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 310 together with a written statement (which need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel) stating
that such Security has never been issued and sold by the Company, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

            SECTION 304. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company may execute, and upon Company
Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as
conclusively the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

            Except in the case of temporary Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), if temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series (accompanied by any unmatured coupons
appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations; provided,
however, that no definitive Bearer Security shall be delivered in exchange for a
temporary Registered Security; and provided further that a definitive Bearer
Security shall be delivered in exchange for a temporary Bearer Security only in
compliance with the conditions set forth in Section 303. Until so exchanged the
temporary Securities of any series shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series.

            If temporary Securities of any series are issued in global form, any
such temporary global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euroclear and Clearstream, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

            Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount

                                       25

<PAGE>

equal to the principal amount of such temporary global Security, executed by the
Company. On or after the Exchange Date such temporary global Security shall be
surrendered by the Common Depositary to the Trustee, as the Company's agent for
such purpose, to be exchanged, in whole or from time to time in part, for
definitive Securities without charge and the Trustee shall authenticate and
deliver, in exchange for each portion of such temporary global Security, an
equal aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such temporary
global Security to be exchanged. The definitive Securities to be delivered in
exchange for any such temporary global Security shall be in bearer form,
registered form, permanent global bearer form or permanent global registered
form, or any combination thereof, as specified as contemplated by Section 301,
and, if any combination thereof is so specified, as requested by the beneficial
owner thereof; provided, however, that, unless otherwise specified in such
temporary global Security, upon such presentation by the Common Depositary, such
temporary global Security is accompanied by a certificate dated the Exchange
Date or a subsequent date and signed by Euroclear as to the portion of such
temporary global Security held for its account then to be exchanged and a
certificate dated the Exchange Date or a subsequent date and signed by
Clearstream as to the portion of such temporary global Security held for its
account then to be exchanged, each in the form set forth in Exhibit A-2 to this
Indenture (or in such other form as may be established pursuant to Section 301);
and provided further that definitive Bearer Securities shall be delivered in
exchange for a portion of a temporary global Security only in compliance with
the requirements of Section 303.

            Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or Clearstream, as the case may be, to request such exchange on his
behalf and delivers to Euroclear or Clearstream, as the case may be, a
certificate in the form set forth in Exhibit A-1 to this Indenture (or in such
other form as may be established pursuant to Section 301), dated no earlier than
15 days prior to the Exchange Date, copies of which certificate shall be
available from the offices of Euroclear and Clearstream, the Trustee, any
Authenticating Agent appointed for such series of Securities and each Paying
Agent. Unless otherwise specified in such temporary global Security, any such
exchange shall be made free of charge to the beneficial owners of such temporary
global Security, except that a Person receiving definitive Securities must bear
the cost of insurance, postage, transportation and the like in the event that
such Person does not take delivery of such definitive Securities in person at
the offices of Euroclear or Clearstream. Definitive Securities in bearer form to
be delivered in exchange for any portion of a temporary global Security shall be
delivered only outside the United States.

            Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear and
Clearstream on such Interest Payment Date upon delivery by Euroclear and
Clearstream to the Trustee of a certificate or certificates in the form set
forth in Exhibit A-2 to this Indenture (or in such other form as may be
established pursuant to Section 301), for credit without further interest
thereon on or after such

                                       26

<PAGE>

Interest Payment Date to the respective accounts of the Persons who are the
beneficial owners of such temporary global Security on such Interest Payment
Date and who have each delivered to Euroclear or Clearstream, as the case may
be, a certificate dated no earlier than 15 days prior to the Interest Payment
Date occurring prior to such Exchange Date in the form set forth in Exhibit A-1
to this Indenture (or in such other form as may be established pursuant to
Section 301). Notwithstanding anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section and of the third
paragraph of Section 303 of this Indenture and the interests of the Persons who
are the beneficial owners of the temporary global Security with respect to which
such certification was made will be exchanged for definitive Securities of the
same series and of like tenor on the Exchange Date or the date of certification
if such date occurs after the Exchange Date, without further act or deed by such
beneficial owners. Except as otherwise provided in this paragraph, no payments
of principal (or premium, if any) or interest, if any, owing with respect to a
beneficial interest in a temporary global Security will be made unless and until
such interest in such temporary global Security shall have been exchanged for an
interest in a definitive Security. Any interest so received by Euroclear and
Clearstream and not paid as herein provided shall be returned to the Trustee
immediately prior to the expiration of two years after such Interest Payment
Date in order to be repaid to the Company in accordance with (but otherwise
subject to) Section 1003.

            SECTION 305. Registration, Registration of Transfer and Exchange.
The Company or the Trustee shall cause to be kept at the Corporate Trust Office
of the Trustee a register for each series of Securities (the registers
maintained in the Corporate Trust Office of the Trustee and in any other office
or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities;
provided, however, that there shall be only one Security Register per series of
Securities. The Security Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. At all
reasonable times, the Security Register shall be open to inspection by the
Trustee. The Trustee is hereby initially appointed as security registrar (the
"Security Registrar") for the purpose of registering Registered Securities and
transfers of Registered Securities as herein provided.

            Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency in a Place of Payment for that
series, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee, one or more new Registered
Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.

            At the option of the Holder, Registered Securities of any series may
be exchanged for other Registered Securities of the same series, of any
authorized denomination and of a like aggregate principal amount, upon surrender
of the Registered Securities to be exchanged at such office or agency. Whenever
any Registered Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Registered
Securities which the Holder making the exchange is entitled to receive. Unless
otherwise specified with

                                       27

<PAGE>

respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.

            If (but only if) expressly permitted in or pursuant to the
applicable Board Resolution and (subject to Section 303) set forth in the
applicable Officer's Certificate, or in any indenture supplemental hereto,
delivered as contemplated by Section 301, at the option of the Holder, Bearer
Securities of any series may be exchanged for Registered Securities of the same
series of any authorized denomination and of a like aggregate principal amount
and tenor, upon surrender of the Bearer Securities to be exchanged at any such
office or agency, with all unmatured coupons and all matured coupons in default
thereto appertaining. If the Holder of a Bearer Security is unable to produce
any such unmatured coupon or coupons or matured coupon or coupons in default,
any such permitted exchange may be effected if the Bearer Securities are
accompanied by payment in funds acceptable to the Company in an amount equal to
the face amount of such missing coupon or coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
is furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to any Paying Agent any such missing coupon in respect of which
such a payment shall have been made, such Holder shall be entitled to receive
the amount of such payment; provided, however, that, except as otherwise
provided in Section 1002, interest represented by coupons shall be payable only
upon presentation and surrender of those coupons at an office or agency located
outside the United States. Notwithstanding the foregoing, in case a Bearer
Security of any series is surrendered at any such office or agency in a
permitted exchange for a Registered Security of the same series and like tenor
after the close of business at such office or agency on (i) any Regular Record
Date and before the opening of business at such office or agency on the relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such office or agency on the related proposed date for payment of
Defaulted Interest, such Bearer Security shall be surrendered without the coupon
relating to such Interest Payment Date or proposed date for payment, as the case
may be, and interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such coupon when due in
accordance with the provisions of this Indenture.

            Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

            Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph. If any beneficial owner of an interest in a
permanent global Security is entitled to exchange such interest for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified as contemplated by Section 301 and provided that
any applicable notice provided in the permanent global Security shall have been
given, then without unnecessary delay but in any event not later than the
earliest date on which such interest may be so exchanged, the Company shall
deliver to the Trustee definitive Securities in aggregate principal amount equal
to the principal amount of such beneficial owner's interest in

                                       28

<PAGE>

such permanent global Security, executed by the Company. On or after the
earliest date on which such interests may be so exchanged, such permanent global
Security shall be surrendered by the Common Depositary or such other depositary
as shall be specified in the Company Order with respect thereto to the Trustee,
as the Company's agent for such purpose, to be exchanged, in whole or from time
to time in part, for definitive Securities without charge, and the Trustee shall
authenticate and deliver, in exchange for each portion of such permanent global
Security, an equal aggregate principal amount of definitive Securities of the
same series of authorized denominations and of like tenor as the portion of such
permanent global Security to be exchanged which, unless the Securities of the
series are not issuable both as Bearer Securities and as Registered Securities,
as specified as contemplated by Section 301, shall be in the form of Bearer
Securities or Registered Securities, or any combination thereof, as shall be
specified by the beneficial owner thereof; provided, however, that no such
exchanges may occur during a period beginning at the opening of business 15 days
before any selection of Securities to be redeemed and ending on the relevant
Redemption Date if the Security for which exchange is requested may be among
those selected for redemption; and provided, further, that no Bearer Security
delivered in exchange for a portion of a permanent global Security shall be
mailed or otherwise delivered to any location in the United States. If a
Registered Security is issued in exchange for any portion of a permanent global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment, as the case may be, only to the Person to whom interest in respect of
such portion of such permanent global Security is payable in accordance with the
provisions of this Indenture.

            All Securities issued upon any registration of transfer or exchange
of Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

            Every Registered Security presented or surrendered for registration
of transfer or for exchange shall (if so required by the Company or the Security
Registrar) be duly endorsed, or be accompanied by a written instrument of
transfer, in form satisfactory to the Company and the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

            If at any time the Depositary for any permanent global Registered
Securities of any series notifies the Company that it is unwilling or unable to
continue as Depositary for such

                                       29

<PAGE>

permanent global Registered Securities or if at any time the Depositary for such
permanent global Registered Securities shall no longer be eligible under
applicable law, the Company shall appoint a successor Depositary eligible under
applicable law with respect to such permanent global Registered Securities. If a
successor Depositary eligible under applicable law for such Registered Global
Securities is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility, the Company will
execute, and the Trustee, upon receipt of the Company's order for the
authentication and delivery of definitive Registered Securities of such series
and tenor, will authenticate and deliver such definitive Registered Securities
of such series and tenor, in any authorized denominations, in an aggregate
principal amount equal to the principal amount of such permanent global
Registered Securities, in exchange for such permanent global Registered
Securities.

            The Company may at any time and in its sole discretion determine
that any permanent global Registered Securities of any series shall no longer be
maintained in global form. In such event the Company will execute, and the
Trustee, upon receipt of the Company's order for the authentication and delivery
of definitive Registered Securities of such series and tenor, will authenticate
and deliver, definitive Registered Securities of such series and tenor in any
authorized denominations, in an aggregate principal amount equal to the
principal amount of such permanent global Registered Securities, in exchange for
such permanent global Registered Securities.

            The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the selection for redemption
of Securities of that series under Section 1103 or 1203 and ending at the close
of business on (A) if Securities of the series are issuable only as Registered
Securities, the day of the mailing of the relevant notice of redemption and (B)
if Securities of the series are issuable as Bearer Securities, the day of the
first publication of the relevant notice of redemption or, if Securities of the
series are also issuable as Registered Securities and there is no publication,
the mailing of the relevant notice of redemption, or (ii) to register the
transfer of or exchange any Registered Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part, or (iii) to exchange any Bearer Security so selected for redemption
except that such a Bearer Security may be exchanged for a Registered Security of
that series and like tenor; provided that such Registered Security shall be
simultaneously surrendered for redemption, or (iv) to issue, register the
transfer of or exchange any Security which has been surrendered for repayment at
the option of the Holder, except the portion, if any, of such Security not to be
so repaid.

            The Trustee shall have no obligation or duty to monitor, determine
or inquire as to compliance with any restrictions on transfer that may be
imposed under this Indenture with respect to the Securities of any series
pursuant to the terms thereof established as contemplated by Section 301 or
under applicable law with respect to any transfer of any interest in any such
Security (including any transfers between or among any depositary (including any
Depositary or Common Depositary), or its nominee, as a Holder of a Security
issued in global form, any participants in such depositary or owners or holders
of beneficial interests in any such global Security) other than to require
delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by, the terms
of such

                                       30

<PAGE>

Securities if and as may be so established in respect of such Securities, and to
examine the same to determine substantial compliance as to form with the express
requirements thereof.

            SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If
any mutilated Security or a Security with a mutilated coupon appertaining to it
is surrendered to the Trustee, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same series
and of like tenor and principal amount and bearing a number not
contemporaneously outstanding, with coupons corresponding to the coupons, if
any, appertaining to the surrendered Security, or, in case any such mutilated
Security or coupon has become or is about to become due and payable, the Company
in its discretion may, instead of issuing a new Security, with coupons
corresponding to the coupons, if any, appertaining to the surrendered Security,
pay such Security or coupon.

            If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and upon Company
Order the Trustee shall authenticate and deliver, in lieu of any such destroyed,
lost or stolen Security or in exchange for the Security for which a destroyed,
lost or stolen coupon appertains (with all appurtenant coupons not destroyed,
lost or stolen), a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding, with
coupons corresponding to the coupons, if any, appertaining to such destroyed,
lost or stolen Security or to the Security to which such destroyed, lost or
stolen coupon appertains.

            Notwithstanding the provisions of the previous two paragraphs, in
case any such mutilated, destroyed, lost or stolen Security or coupon has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, with coupons corresponding to the coupons, if
any, appertaining to such mutilated, destroyed, lost or stolen Security or to
the Security to which such mutilated, destroyed, lost or stolen coupon
appertains, pay such Security or coupon; provided, however, that payment of
principal of (and premium, if any) and interest, if any, on Bearer Securities
shall, except as otherwise provided in Section 1002, be payable only at an
office or agency located outside the United States and, unless otherwise
specified as contemplated by Section 301, any interest on Bearer Securities
shall be payable only upon presentation and surrender of the coupons
appertaining thereto.

            Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

            Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen
Security or in exchange for a Security to which a mutilated, destroyed, lost or
stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the mutilated, destroyed, lost or
stolen Security and its coupons, if any, or the mutilated, destroyed, lost or
stolen coupon shall be

                                       31

<PAGE>

at any time enforceable by anyone, and shall be entitled to all the benefits of
this Indenture equally and proportionately with any and all other Securities of
that series and their coupons, if any, duly issued hereunder.

            The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities or coupons.

            SECTION 307. Payment of Interest; Interest Rights Preserved;
Optional Interest Reset. (a) Unless otherwise provided as contemplated by
Section 301 with respect to any series of Securities, interest, if any, on any
Registered Security which is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name such
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest at the office or agency of
the Company maintained for such purpose pursuant to Section 1002; provided,
however, that each installment of interest, if any, on any Registered Security
may at the Company's option be paid by (i) mailing a check for such interest,
payable to or upon the written order of the Person entitled thereto pursuant to
Section 309, to the address of such Person as it appears on the Security
Register or (ii) transfer to an account located in the United States maintained
by the payee.

            Unless otherwise provided as contemplated by Section 301 with
respect to the Securities of any series, payment of interest, if any, may be
made, in the case of a Bearer Security, by transfer to an account located
outside the United States maintained by the payee.

            Any interest on any Registered Security of any series which is
payable, but is not punctually paid or duly provided for, on any Interest
Payment Date shall forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder, and such defaulted
interest and, if applicable, interest on such defaulted interest (to the extent
lawful) at the rate specified in the Securities of such series (such defaulted
interest and, if applicable, interest thereon herein collectively called
"Defaulted Interest") may be paid by the Company, at its election in each case,
as provided in clause (1) or (2) below:

            (1)   The Company may elect to make payment of any Defaulted
      Interest to the Persons in whose names the Registered Securities of such
      series (or their respective Predecessor Securities) are registered at the
      close of business on a Special Record Date for the payment of such
      Defaulted Interest, which shall be fixed in the following manner. The
      Company shall notify the Trustee in writing of the amount of Defaulted
      Interest proposed to be paid on each Registered Security of such series
      and the date of the proposed payment, and at the same time the Company
      shall deposit with the Trustee an amount of money in the Currency in which
      the Securities of such series are payable (except as otherwise specified
      pursuant to Section 301 for the Securities of such series and except, if
      applicable, as provided in Sections 312(b), 312(d) and 312(e)) equal to
      the aggregate amount proposed to be paid in respect of such Defaulted
      Interest or shall make arrangements satisfactory to the Trustee for such
      deposit on or prior to the date of the proposed payment, such money when
      deposited to be held in trust for the benefit of the Persons entitled to
      such Defaulted Interest as in this clause provided. Thereupon the Trustee
      shall fix a Special Record Date for the payment of such Defaulted Interest
      which

                                       32

<PAGE>

      shall be not more than 15 days and not less than 10 days prior to the date
      of the proposed payment and not less than 10 days after the receipt by the
      Trustee of the notice of the proposed payment. The Trustee shall promptly
      notify the Company of such Special Record Date and, in the name and at the
      expense of the Company, shall cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be given in the
      manner provided in Section 106, not less than 10 days prior to such
      Special Record Date. Notice of the proposed payment of such Defaulted
      Interest and the Special Record Date therefor having been so given, such
      Defaulted Interest shall be paid to the Persons in whose name the
      Registered Securities of such series (or their respective Predecessor
      Securities) are registered at the close of business on such Special Record
      Date and shall no longer be payable pursuant to the following clause (2).

            (2)   The Company may make payment of any Defaulted Interest on the
      Registered Securities of any series in any other lawful manner not
      inconsistent with the requirements of any securities exchange on which
      such Securities may be listed, and upon such notice as may be required by
      such exchange, if, after notice given by the Company to the Trustee of the
      proposed payment pursuant to this clause, such manner of payment shall be
      deemed practicable by the Trustee.

            (b)   The provisions of this Section 307(b) may be made applicable
to any series of Securities pursuant to Section 301 (with such modifications,
additions or substitutions as may be specified pursuant to such Section 301).
The interest rate (or the spread or spread multiplier used to calculate such
interest rate, if applicable) on any Security of such series may be reset by the
Company on the date or dates specified on the face of such Security (each an
"Optional Reset Date"). The Company may exercise such option with respect to
such Security by notifying the Trustee of such exercise at least 50 but not more
than 60 days prior to an Optional Reset Date for such Note. Not later than 40
days prior to each Optional Reset Date, the Trustee shall transmit, in the
manner provided for in Section 106, to the Holder of any such Security a notice
(the "Reset Notice") indicating whether the Company has elected to reset the
interest rate (or the spread or spread multiplier used to calculate such
interest rate, if applicable), and if so (i) such new interest rate (or such new
spread or spread multiplier, if applicable) and (ii) the provisions, if any, for
redemption during the period from such Optional Reset Date to the next Optional
Reset Date or if there is no such next Optional Reset Date, to the Stated
Maturity Date of such Security (each such period a "Subsequent Interest
Period"), including the date or dates on which or the period or periods during
which and the price or prices at which such redemption may occur during the
Subsequent Interest Period.

            Notwithstanding the foregoing, not later than 20 days prior to the
Optional Reset Date, the Company may, at its option, revoke the interest rate
(or the spread or spread multiplier used to calculate such interest rate, if
applicable) provided for in the Reset Notice and establish an interest rate (or
a spread or spread multiplier used to calculate such interest rate, if
applicable) that is higher than the interest rate (or the spread or spread
multiplier, if applicable) provided for in the Reset Notice, for the Subsequent
Interest Period by causing the Trustee to transmit, in the manner provided for
in Section 106, notice of such higher interest rate (or such higher spread or
spread multiplier, if applicable) to the Holder of such Security. Such notice
shall be irrevocable. All Securities with respect to which the interest rate (or
the spread or spread multiplier used to calculate such interest rate, if
applicable) is reset on an Optional Reset Date, and with respect to

                                       33

<PAGE>

which the Holders of such Securities have not tendered such Securities for
repayment (or have validly revoked any such tender) pursuant to the next
succeeding paragraph, will bear such higher interest rate (or such higher spread
or spread multiplier, if applicable).

            The Holder of any such Security will have the option to elect
repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest
accrued to such Optional Reset Date. In order to obtain repayment on an Optional
Reset Date, the Holder must follow the procedures set forth in Article Thirteen
for repayment at the option of Holders except that the period for delivery or
notification to the Trustee shall be at least 25 but not more than 35 days prior
to such Optional Reset Date and except that, if the Holder has tendered any
Security for repayment pursuant to the Reset Notice, the Holder may, by written
notice to the Trustee, revoke such tender or repayment until the close of
business on the tenth day before such Optional Reset Date.

            Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

            SECTION 308. Optional Extension of Stated Maturity. The provisions
of this Section 308 may be made applicable to any series of Securities pursuant
to Section 301 (with such modifications, additions or substitutions as may be
specified pursuant to such Section 301). The Stated Maturity of any Security of
such series may be extended at the option of the Company for the period or
periods specified on the face of such Security (each an "Extension Period") up
to but not beyond the date (the "Final Maturity") set forth on the face of such
Security. The Company may exercise such option with respect to any Security by
notifying the Trustee of such exercise at least 50 but not more than 60 days
prior to the Stated Maturity of such Security in effect prior to the exercise of
such option (the "Original Stated Maturity"). If the Company exercises such
option, the Trustee shall transmit, in the manner provided for in Section 106,
to the Holder of such Security not later than 40 days prior to the Original
Stated Maturity a notice (the "Extension Notice") indicating (i) the election of
the Company to extend the Stated Maturity, (ii) the new Stated Maturity, (iii)
the interest rate, if any, applicable to the Extension Period and (iv) the
provisions, if any, for redemption during such Extension Period. Upon the
Trustee's transmittal of the Extension Notice, the Stated Maturity of such
Security shall be extended automatically and, except as modified by the
Extension Notice and as described in the next paragraph, such Security will have
the same terms as prior to the transmittal of such Extension Notice.

            Notwithstanding the foregoing, not later than 20 days before the
Original Stated Maturity of such Security, the Company may, at its option,
revoke the interest rate provided for in the Extension Notice and establish a
higher interest rate for the Extension Period by causing the Trustee to
transmit, in the manner provided for in Section 106, notice of such higher
interest rate to the Holder of such Security. Such notice shall be irrevocable.
All Securities with respect to which the Stated Maturity is extended will bear
such higher interest rate.

            If the Company extends the Maturity of any Security, the Holder will
have the option to elect repayment of such Security by the Company on the
Original Stated Maturity at a

                                       34

<PAGE>

price equal to the principal amount thereof, plus interest accrued to such date.
In order to obtain repayment on the Original Stated Maturity once the Company
has extended the Maturity thereof, the Holder must follow the procedures set
forth in Article Thirteen for repayment at the option of Holders, except that
the period for delivery or notification to the Trustee shall be at least 25 but
not more than 35 days prior to the Original Stated Maturity and except that, if
the Holder has tendered any Security for repayment pursuant to an Extension
Notice, the Holder may by written notice to the Trustee revoke such tender for
repayment until the close of business on the tenth day before the Original
Stated Maturity.

            SECTION 309. Persons Deemed Owners. Prior to due presentment of a
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Registered Security for
the purpose of receiving payment of principal of (and premium, if any) and
(subject to Sections 305 and 307) interest, if any, on such Security and for all
other purposes whatsoever, whether or not such Security be overdue, and none of
the Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

            Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery. The Company, the Trustee and any agent of the Company or
the Trustee may treat the bearer of any Bearer Security and the bearer of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupons be overdue, and none of the
Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

            None of the Company, the Trustee, any Paying Agent or the Security
Registrar shall have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests. The
Company, the Trustee and the Securities Registrar shall be entitled to deal with
any depositary (including any Depositary or Common Depositary), and any nominee
thereof, that is the Holder of any such global Security for all purposes of this
Indenture relating to such global Security (including the payment of principal,
premium, if any, and interest and Additional Amounts, if any, and the giving of
instructions or directions by or to the owner or holder of a beneficial
ownership interest in such global Security) as the sole Holder of such global
Security and shall have no obligations to the beneficial owners thereof. None of
the Company, the Trustee, any Paying Agent or the Security Registrar shall have
any responsibility or liability for any acts or omissions of any such depositary
with respect to such global Security, for the records of any such depositary,
including records in respect of beneficial ownership interests in respect of any
such global Security, for any transactions between such depositary and any
participant in such depositary or between or among any such depositary, any such
participant and/or any holder or owner of a beneficial interest in such global
Security or for any transfers of beneficial interests in any such global
Security.

            Notwithstanding the foregoing, with respect to any global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving

                                       35

<PAGE>

effect to any written certification, proxy or other authorization furnished by
any depositary (including any Depositary or Common Depositary), as a Holder,
with respect to such global Security or impair, as between such depositary and
owners of beneficial interests in such global Security, the operation of
customary practices governing the exercise of the rights of such depositary (or
its nominee) as Holder of such global Security.

            SECTION 310. Cancellation. All Securities and coupons surrendered
for payment, redemption, repayment at the option of the Holder, registration of
transfer or exchange or for credit against any current or future sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee. All Securities and coupons so delivered to the Trustee shall be
promptly cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
cancelled by the Trustee. If the Company shall so acquire any of the Securities,
however, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture. All cancelled
Securities held by the Trustee shall be disposed of by the Trustee in accordance
with its customary procedures and, if requested by the Company in writing,
certification of their disposal delivered to the Company, unless by Company
Order the Company shall timely direct that cancelled Securities be returned to
it.

            SECTION 311. Computation of Interest. Except as otherwise specified
as contemplated by Section 301 with respect to any Securities, interest, if any,
on the Securities of each series shall be computed on the basis of a 360-day
year of twelve 30-day months.

            SECTION 312. Currency and Manner of Payments in Respect of
Securities. (a) With respect to Registered Securities of any series not
permitting the election provided for in paragraph (b) below or the Holders of
which have not made the election provided for in paragraph (b) below, and with
respect to Bearer Securities of any series, except as provided in paragraph (d)
below, payment of the principal of (and premium, if any) and interest, if any,
on any Registered or Bearer Security of such series will be made in the Currency
in which such Registered Security or Bearer Security, as the case may be, is
payable. The provisions of this Section 312 may be modified or superseded with
respect to any Securities pursuant to Section 301.

            (b)   It may be provided pursuant to Section 301 with respect to
Registered Securities of any series that Holders shall have the option, subject
to paragraphs (d) and (e) below, to receive payments of principal of (or
premium, if any) or interest, if any, on such Registered Securities in any of
the Currencies which may be designated for such election by delivering to the
Trustee a written election with signature guarantees and in the applicable form
established pursuant to Section 301, not later than the close of business on the
Election Date immediately preceding the applicable payment date. If a Holder so
elects to receive such payments in any such Currency, such election will remain
in effect for such Holder or any

                                       36

<PAGE>

transferee of such Holder until changed by such Holder or such transferee by
written notice to the Trustee (but any such change must be made not later than
the close of business on the Election Date immediately preceding the next
payment date to be effective for the payment to be made on such payment date and
no such change of election may be made with respect to payments to be made on
any Registered Security of such series with respect to which an Event of Default
has occurred or with respect to which the Company has deposited funds pursuant
to Article Four or Fourteen or with respect to which a notice of redemption has
been given by the Company or a notice of option to elect repayment has been sent
by such Holder or such transferee). Any Holder of any such Registered Security
who shall not have delivered any such election to the Trustee not later than the
close of business on the applicable Election Date will be paid the amount due on
the applicable payment date in the relevant Currency as provided in Section
312(a). The Trustee shall notify the Exchange Rate Agent as soon as practicable
after the Election Date of the aggregate principal amount of Registered
Securities for which Holders have made such written election.

            (c)   Unless otherwise specified pursuant to Section 301, if the
election referred to in paragraph (b) above has been provided for pursuant to
Section 301, then, unless otherwise specified pursuant to Section 301, not later
than the fourth Business Day after the Election Date for each payment date for
Registered Securities of any series, the Exchange Rate Agent will deliver to the
Company a written notice specifying, in the Currency in which Registered
Securities of such series are payable, the respective aggregate amounts of
principal of (and premium, if any) and interest, if any, on the Registered
Securities to be paid on such payment date, specifying the amounts in such
Currency so payable in respect of the Registered Securities as to which the
Holders of Registered Securities of such series shall have elected to be paid in
another Currency as provided in paragraph (b) above. If the election referred to
in paragraph (b) above has been provided for pursuant to Section 301 and if at
least one Holder has made such election, then, unless otherwise specified
pursuant to Section 301, on the second Business Day preceding such payment date
the Company will deliver to the Trustee for such series of Registered Securities
an Exchange Rate Officer's Certificate in respect of the Dollar or Foreign
Currency payments to be made on such payment date. Unless otherwise specified
pursuant to Section 301, the Dollar or Foreign Currency amount receivable by
Holders of Registered Securities who have elected payment in a Currency as
provided in paragraph (b) above shall be determined by the Company on the basis
of the applicable Market Exchange Rate in effect on the third Business Day (the
"Valuation Date") immediately preceding each payment date, and such
determination shall be conclusive and binding for all purposes, absent manifest
error.

            (d)   If a Conversion Event occurs with respect to a Foreign
Currency in which any of the Securities are denominated or payable other than
pursuant to an election provided for pursuant to paragraph (b) above, then with
respect to each date for the payment of principal of (and premium, if any) and
interest, if any, on the applicable Securities denominated or payable in such
Foreign Currency occurring after the last date on which such Foreign Currency
was used (the "Conversion Date"), the Dollar shall be the Currency of payment
for use on each such payment date. Unless otherwise specified pursuant to
Section 301, the Dollar amount to be paid by the Company to the Trustee and by
the Trustee or any Paying Agent to the Holders of such Securities with respect
to such payment date shall be, in the case of a Foreign Currency other than a
currency unit, the Dollar Equivalent of the Foreign Currency or, in the case of
a currency

                                       37

unit, the Dollar Equivalent of the Currency Unit, in each case as determined by
the Exchange Rate Agent in the manner provided in paragraph (f) or (g) below.

            (e)   Unless otherwise specified pursuant to Section 301, if the
Holder of a Registered Security denominated in any Currency shall have elected
to be paid in another Currency as provided in paragraph (b) above, and a
Conversion Event occurs with respect to such elected Currency, such Holder shall
receive payment in the Currency in which payment would have been made in the
absence of such election; and if a Conversion Event occurs with respect to the
Currency in which payment would have been made in the absence of such election,
such Holder shall receive payment in Dollars as provided in paragraph (d) above.

            (f)   The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Exchange Rate Agent and shall be obtained for each subsequent
payment date by converting the specified Foreign Currency into Dollars at the
Market Exchange Rate on the Conversion Date.

            (g)   The "Dollar Equivalent of the Currency Unit" shall be
determined by the Exchange Rate Agent and subject to the provisions of paragraph
(h) below shall be the sum of each amount obtained by converting the Specified
Amount of each Component Currency into Dollars at the Market Exchange Rate for
such Component Currency on the Valuation Date with respect to each payment.

            (h)   For purposes of this Section 312 the following terms shall
have the following meanings:

            A "Component Currency" shall mean any Currency which, on the
      Conversion Date, was a component currency of the relevant currency unit,
      including, but not limited to, the Euro.

            A "Specified Amount" of a Component Currency shall mean the number
      of units of such Component Currency or fractions thereof which were
      represented in the relevant currency unit, including, but not limited to,
      the Euro, on the Conversion Date. If after the Conversion Date the
      official unit of any Component Currency is altered by way of combination
      or subdivision, the Specified Amount of such Component Currency shall be
      divided or multiplied in the same proportion. If after the Conversion Date
      two or more Component Currencies are consolidated into a single currency,
      the respective Specified Amounts of such Component Currencies shall be
      replaced by an amount in such single Currency equal to the sum of the
      respective Specified Amounts of such consolidated Component Currencies
      expressed in such single Currency, and such amount shall thereafter be a
      Specified Amount and such single Currency shall thereafter be a Component
      Currency. If after the Conversion Date any Component Currency shall be
      divided into two or more currencies, the Specified Amount of such
      Component Currency shall be replaced by amounts of such two or more
      currencies, having an aggregate Dollar Equivalent value at the Market
      Exchange Rate on the date of such replacement equal to the Dollar
      Equivalent value of the Specified Amount of such former Component Currency
      at the Market Exchange Rate immediately before such division and such
      amounts shall thereafter be Specified Amounts and such currencies shall
      thereafter be

                                       38

<PAGE>

      Component Currencies. If, after the Conversion Date of the relevant
      currency unit, including, but not limited to, the Euro, a Conversion Event
      (other than any event referred to above in this definition of "Specified
      Amount") occurs with respect to any Component Currency of such currency
      unit and is continuing on the applicable Valuation Date, the Specified
      Amount of such Component Currency shall, for purposes of calculating the
      Dollar Equivalent of the Currency Unit, be converted into Dollars at the
      Market Exchange Rate in effect on the Conversion Date of such Component
      Currency.

            "Election Date" shall mean the date for any series of Registered
      Securities as specified pursuant to clause (13) of Section 301 by which
      the written election referred to in paragraph (b) above may be made.

            All decisions and determinations of the Exchange Rate Agent
regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent
of the Currency Unit, the Market Exchange Rate and changes in the Specified
Amounts as specified above shall be in its sole discretion and shall, in the
absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Company, the Trustee and all Holders of such Securities
denominated or payable in the relevant Currency. The Exchange Rate Agent shall
promptly give written notice to the Company and the Trustee of any such decision
or determination.

            In the event that the Company determines in good faith that a
Conversion Event has occurred with respect to a Foreign Currency, the Company
will immediately give written notice thereof to the Trustee and to the Exchange
Rate Agent (and the Trustee will promptly thereafter give notice in the manner
provided for in Section 106 to the affected Holders) specifying the Conversion
Date. In the event the Company so determines that a Conversion Event has
occurred with respect to the Euro or any other currency unit in which Securities
are denominated or payable, the Company will immediately give written notice
thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will
promptly thereafter give notice in the manner provided for in Section 106 to the
affected Holders) specifying the Conversion Date and the Specified Amount of
each Component Currency on the Conversion Date. In the event the Company
determines in good faith that any subsequent change in any Component Currency as
set forth in the definition of Specified Amount above has occurred, the Company
will similarly give written notice to the Trustee and the Exchange Rate Agent.
The Trustee shall be fully justified and protected in relying and acting upon
information received by it from the Company and the Exchange Rate Agent and
shall not otherwise have any duty or obligation to determine the accuracy or
validity of such information independent of the Company or the Exchange Rate
Agent.

            SECTION 313. Appointment and Resignation of Successor Exchange Rate
Agent. (a) Unless otherwise specified pursuant to Section 301, if and so long as
the Securities of any series (i) are denominated in a Currency other than
Dollars or (ii) may be payable in a Currency other than Dollars, or so long as
it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one Exchange Rate Agent. The Company will cause the Exchange Rate Agent
to make the necessary foreign exchange determinations at the time and in the
manner specified pursuant to Section 301 for the purpose of determining the
applicable rate of exchange and, if applicable, for the purpose of converting
the issued Currency into the applicable payment

                                       39

<PAGE>

Currency for the payment of principal (and premium, if any) and interest, if
any, pursuant to Section 312.

            (b)   No resignation of the Exchange Rate Agent and no appointment
of a successor Exchange Rate Agent pursuant to this Section shall become
effective until the acceptance of appointment by the successor Exchange Rate
Agent as evidenced by a written instrument delivered to the Company and the
Trustee.

            (c)   If the Exchange Rate Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Exchange
Rate Agent for any cause with respect to the Securities of one or more series,
the Company, by or pursuant to a Board Resolution, shall promptly appoint a
successor Exchange Rate Agent or Exchange Rate Agents with respect to the
Securities of that or those series (it being understood that any such successor
Exchange Rate Agent may be appointed with respect to the Securities of one or
more or all of such series and that, unless otherwise specified pursuant to
Section 301, at any time there shall only be one Exchange Rate Agent with
respect to the Securities of any particular series that are originally issued by
the Company on the same date and that are initially denominated and/or payable
in the same Currency).

            SECTION 401. Satisfaction and Discharge of Indenture. This Indenture
shall upon Company Request cease to be of further effect with respect to any
series of Securities specified in such Company Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series expressly provided for herein or pursuant hereto and any right to receive
Additional Amounts as contemplated by Section 1005) and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture as to such series when

            (1)   either

                  (A)   all Securities of such series theretofore authenticated

            money has theretofore been deposited in trust with the Trustee or

                  (B)   all Securities of such series and, in the case of (i) or
            (ii) below, any coupons appertaining thereto not theretofore
            delivered to the Trustee for cancellation

                        (i)   have become due and payable, or

                        (ii)  will become due and payable at their Stated
                  Maturity within one year, or

                        (iii) if redeemable at the option of the Company, are to
                  be called for redemption within one year under arrangements
                  satisfactory to the Trustee for the giving of notice of
                  redemption by the Trustee in the name, and at the expense, of
                  the Company,

            and the Company, in the case of (i), (ii) or (iii) above, has
            irrevocably deposited or caused to be deposited with the Trustee as
            trust funds in trust for such purpose an amount in the Currency in
            which the Securities of such series are payable, sufficient to pay
            and discharge the entire indebtedness on such Securities not
            theretofore delivered to the Trustee for cancellation, for principal
            (and premium, if any) and interest, if any, to the date of such
            deposit (in the case of Securities which have become due and
            payable) or to the Stated Maturity or Redemption Date, as the case
            may be;

            (2)   the Company has paid or caused to be paid all other sums
      payable hereunder by the Company; and

            (3)   the Company has delivered to the Trustee an Officer's
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent herein provided for relating to the satisfaction and discharge
      of this Indenture as to such series have been complied with.

            Notwithstanding the satisfaction and discharge of this Indenture,
the obligations of the Company to the Trustee under Section 606, the obligations
of the Trustee to any Authenticating Agent under Section 611 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last

payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium, if any) and interest, if any,
for whose payment such money has been deposited with the Trustee; but such money
need not be segregated from other funds except to the extent required by law.
Money so held in trust (i) is not subject to Article Sixteen and (ii) is subject
to the Trustee's rights under Section 606.

                                    REMEDIES

            SECTION 501. Events of Default. "Event of Default", wherever used
herein with respect to Securities of any series, means any one of the following
events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

            (1)   default in the payment of any interest on any Security of that
      series, or any related coupon, when such interest or coupon becomes due
      and payable, and continuance of such default for a period of 30 days; or

            (2)   default in the payment of the principal of (or premium, if
      any, on) any Security of that series at its Maturity; or

            (3)   default in the deposit of any sinking fund payment, when and
      as due by the terms of the Securities of that series and Article Twelve;
      or

            (4)   default in the performance, or breach, of any covenant or
      agreement of the Company in this Indenture which affects or is applicable
      to the Securities of that series (other than a default in the performance,
      or breach of a covenant or agreement which is specifically dealt with
      elsewhere in this Section, and continuance of such default or breach for a
      period of 60 days after there has been given, by registered or certified
      mail, to the Company by the Trustee or to the Company and the Trustee by
      the Holders of at least 25% in principal amount of all Outstanding
      Securities of that series a written notice specifying such default or
      breach and requiring it to be remedied and stating that such notice is a
      "Notice of Default" hereunder; or

            (5)   the entry of a decree or order by a court having jurisdiction
      in the premises adjudging the Company as bankrupt or insolvent, or
      approving as properly filed a petition seeking reorganization,
      arrangement, adjustment or composition of or in respect of the Company
      under the Federal Bankruptcy Code or any other applicable federal or state
      law, or appointing a receiver, liquidator, assignee, trustee, sequestrator
      (or other similar official) of the Company or of any substantial part of
      its property, or ordering the winding up or liquidation of its affairs,
      and the continuance of any such decree or order unstayed and in effect for
      a period of 90 consecutive days; or

            (6)   the institution by the Company of proceedings to be
      adjudicated a bankrupt or insolvent, or the consent by it to the
      institution of bankruptcy or insolvency proceedings against it, or the
      filing by it of a petition or answer or consent seeking reorganization or
      relief under the Federal Bankruptcy Code or any other applicable federal
      or state law, or the consent by it to the filing of any such petition or
      to the appointment of a receiver, liquidator, assignee, trustee,
      sequestrator (or other similar official) of the Company or of any
      substantial part of its property, or the making by it of

                                       42

<PAGE>

      an assignment for the benefit of creditors, or the admission by it in
      writing of its inability to pay its debts generally as they become due; or

            (7)   any other Event of Default provided pursuant to Section 301 or
      901 with respect to Securities of that series.

            SECTION 502. Acceleration of Maturity; Rescission and Annulment. If
an Event of Default described in clause (1), (2), (3), (4) or (7) of Section 501
with respect to Securities of any series at the time Outstanding occurs and is
continuing, then in every such case the Trustee or the Holders of not less than
25% in principal amount of the Outstanding Securities of that series may declare
the principal amount (or, if the Securities of that series are Original Issue
Discount Securities or Indexed Securities, such portion of the principal amount
as may be specified in the terms of that series) of all of the Securities of
that series to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), and upon any such declaration
such principal amount (or specified portion thereof) shall become immediately
due and payable. If an Event of Default specified in Sections 501(5) or 501(6)
occurs and is continuing, then the principal amount of all the Securities then
Outstanding (or, if any such Securities are Original Issue Discount Securities
or Indexed Securities, such portion of the principal amount as may be specified
in the terms of that series) shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.

            At any time after a declaration of acceleration with respect to
Securities of any series (or of all series, as the case may be) has been made
and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter provided in this Article, the Holders of a
majority in principal amount of the Outstanding Securities of that series (or of
all series, as the case may be), by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

            (1)   the Company has paid or deposited with the Trustee a sum
      sufficient to pay in the Currency in which the Securities of such series
      are payable (except as otherwise specified pursuant to Section 301 for the
      Securities of such series and except, if applicable, as provided in
      Sections 312(b), 312(d) and 312(e)),

                  (A)   all overdue interest, if any, on all Outstanding
            Securities of that series (or of all series, as the case may be) and
            any related coupons,

                  (B)   all unpaid principal of (and premium, if any) any
            Outstanding Securities of that series (or of all series, as the case
            may be) which has become due otherwise than by such declaration of
            acceleration, and interest on such unpaid principal at the rate or
            rates prescribed therefor in such Securities,

                  (C)   interest on overdue interest, if any, at the rate or
            rates prescribed therefor in such Securities, and

                  (D)   all sums paid or advanced by the Trustee hereunder and
            the reasonable compensation, expenses, disbursements and advances of
            the Trustee, its agents and counsel; and

                                       43

<PAGE>

            (2)   all Events of Default with respect to Securities of that
      series (or of all series, as the case may be), other than the non-payment
      of amounts of principal of (or premium, if any, on) or interest on
      Securities of that series (or of all series, as the case may be) which
      have become due solely by such declaration of acceleration, have been
      cured or waived as provided in Section 513. No such rescission shall
      affect any subsequent default or impair any right consequent thereon.

            SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee. The Company covenants that if

            (1)   default is made in the payment of any installment of interest
      on any Security and any related coupon when such interest becomes due and
      payable and such default continues for a period of 30 days, or

            (2)   default is made in the payment of the principal of (or
      premium, if any, on) any Security at the Maturity thereof and such default
      continues for a period of 5 Business Days,

then the Company will, upon demand of the Trustee, pay to the Trustee for the
benefit of the Holders of such Securities and coupons, the whole amount then due
and payable on such Securities and coupons for principal (and premium, if any)
and interest, if any, and interest on any overdue principal (and premium, if
any) and on any overdue interest, at the rate or rates prescribed therefor in
such Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

            If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

            If an Event of Default with respect to Securities of any series (or
of all series, as the case may be) occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities of such series (or of all series, as the case may be) by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

            SECTION 504. Trustee May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Securities shall then be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made

                                       44

<PAGE>

any demand on the Company for the payment of overdue principal, premium, if any,
or interest) shall be entitled and empowered, by intervention in such proceeding
or otherwise,

            (i)   to file and prove a claim for the whole amount of principal
      (and premium, if any), or such portion of the principal amount of any
      series of Original Issue Discount Securities or Indexed Securities as may
      be specified in the terms of such series, and interest, if any, owing and
      unpaid in respect of the Securities and to file such other papers or
      documents as may be necessary or advisable in order to have the claims of
      the Trustee (including any claim for the reasonable compensation,
      expenses, disbursements and advances of the Trustee, its agents and
      counsel) and of the Holders allowed in such judicial proceeding, and

            (ii)  to collect and receive any moneys or other property payable or
      deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 606.

            Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

            SECTION 505. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities and
coupons in respect of which such judgment has been recovered.

the Trustee pursuant to this Article and any money or other property
distributable in respect of the Company's obligations under this Indenture after
an Event of Default shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on
account of principal (or premium, if any) or interest, if any, upon presentation

      principal of (and premium, if any) and interest, if any, on the Securities
      and coupons in respect of which or for the benefit of which such money has

      for principal (and premium, if any) and interest, if any, respectively;
      and

            Third: The balance, if any, to the Person or Persons entitled
      thereto.

            SECTION 507. Limitation on Suits. No Holder of any Security of any
series or any related coupons shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder, unless

            (1)   such Holder has previously given written notice to the Trustee
      of a continuing Event of Default with respect to the Securities of that
      series;

            (2)   the Holders of not less than 25% in principal amount of the
      Outstanding Securities of that series in the case of any Event of Default
      described in clause (1), (2), (3), (4), or (7) of Section 501, or, in the
      case of any Event of Default described in clause (5) or (6) of Section
      501, the Holders of not less than 25% in principal amount of all
      Outstanding Securities, shall have made written request to the Trustee to
      institute proceedings in respect of such Event of Default in its own name
      as Trustee hereunder;

            (3)   such Holder or Holders have offered to the Trustee reasonable
      indemnity satisfactory to it against the costs, expenses and liabilities
      to be incurred in compliance with such request;

            (4)   the Trustee for 60 days after its receipt of such notice,
      request and offer of indemnity has failed to institute any such
      proceeding; and

            (5)   no direction inconsistent with such written request has been
      given to the Trustee during such 60-day period by the Holders of a
      majority or more in principal amount of the Outstanding Securities of that
      series in the case of any Event of Default described in clause (1), (2),
      (3), (4) or (7) of Section 501, or, in the case of any Event of Default
      described in clause (5) or (6) of Section 501, by the Holders of a
      majority or more in principal amount of all Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Securities of the same series, in the case of any Event of Default
described in clause (1), (2), (3), (4) or (7) of Section 501, or of Holders of
all Securities in the case of any Event of Default described in clause (5) or
(6) of Section 501, or to obtain or to seek to obtain priority or preference
over any other of such Holders or to enforce any right under this Indenture,
except in the manner herein provided and for the equal and ratable benefit of
all Holders of Securities of the same series, in the case of any Event of
Default described in clause (1), (2), (3), (4) or (7) of Section 501, or of
Holders of all Securities in the case of any Event of Default described in
clause (5) or (6) of Section 501.

<PAGE>

            SECTION 508. Unconditional Right of Holders to Receive Principal,
Premium and Interest. Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment, as provided herein (including, if applicable,
Article Fourteen) and in such Security, of the principal of (and premium, if
any) and (subject to Section 307) interest, if any, on, such Security or payment
of such coupon on the respective Stated Maturities expressed in such Security or
coupon (or, in the case of redemption, on the Redemption Date) and to institute
suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

            SECTION 509. Restoration of Rights and Remedies. If the Trustee or
any Holder has instituted any proceeding to enforce any right or remedy under
this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then
and in every such case, subject to any determination in such proceeding, the
Company, the Trustee and the Holders of Securities and coupons shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.

            SECTION 510. Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or coupons in the last paragraph of Section 306, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders of Securities or coupons is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

            SECTION 511. Delay or Omission Not Waiver. No delay or omission of
the Trustee or of any Holder of any Security or coupon to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

            SECTION 512. Control by Holders. With respect to the Securities of
any series, the Holders of not less than a majority in principal amount of the
Outstanding Securities of such series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee, relating to
or arising under clause (1), (2), (3), (4) or (7) of Section 501, and, with
respect to all Securities, the Holders of not less than a majority in principal
amount of all Outstanding Securities shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee, not relating
to or arising under clause (1), (2), (3), (4) or (7) of Section 501, provided
that in each case

                                       47

<PAGE>

            (1)   such direction shall not be in conflict with any rule of law
      or with this Indenture,

            (2)   the Trustee may take any other action deemed proper by the
      Trustee which is not inconsistent with such direction, and

            (3)   the Trustee need not take any action which might involve it in
      personal liability or be unjustly prejudicial to the Holders of Securities
      of such series not consenting.

            SECTION 513. Waiver of Past Defaults. Subject to Section 502, the
Holders of not less than a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities of
such series waive any past default described in clause (1), (2), (3), (4) or (7)
of Section 501 (or, in the case of a default described in clause (5) or (6) of
Section 501, the Holders of not less than a majority in principal amount of all
Outstanding Securities may waive any such past default), and its consequences,
except a default

            (1)   in respect of the payment of the principal of (or premium, if
      any) or interest, if any, on any Security or any related coupon, or

            (2)   in respect of a covenant or provision hereof which under
      Article Nine cannot be modified or amended without the consent of the
      Holder of each Outstanding Security of such series affected.

            Upon any such waiver, any such default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

            SECTION 514. Waiver of Stay or Extension Laws. The Company covenants
(to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this
Indenture; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                                   ARTICLE SIX

                                   THE TRUSTEE

            SECTION 601. Notice of Defaults. Within 90 days after the occurrence
of any Default hereunder with respect to the Securities of any series, the
Trustee shall transmit in the manner and to the extent provided in TIA Section
313(c), notice of such default hereunder known to a Responsible Officer of the
Trustee, unless such Default shall have been cured or waived; provided, however,
that, except in the case of a Default in the payment of the principal

                                       48

<PAGE>

of (or premium, if any) or interest, if any, on any Security of such series or
in the payment of any sinking fund installment with respect to Securities of
such series, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interest of the Holders of
Securities of such series and any related coupons; and provided further that in
the case of any Default of the character specified in Section 501(4) with
respect to Securities of such series, no such notice to Holders shall be given
until at least 30 days after the occurrence thereof.

            SECTION 602. Certain Duties, Responsibilities and Rights of Trustee.
Subject to the provisions of TIA Sections 315(a) through 315(d):

            (1)   except during the continuance of an Event of Default,

                  (a)   the Trustee undertakes to perform such duties and only
                        such duties as are specifically set forth in this
                        Indenture, and no implied covenants or obligations shall
                        be read into this Indenture against the Trustee; and

                  (b)   in the absence of bad faith on its part, the Trustee may
                        conclusively rely, as to the truth of the statements and
                        the correctness of the opinions expressed therein, upon
                        certificates or opinions furnished to the Trustee and
                        conforming to the requirements of this Indenture; but in
                        the case of any such certificates or opinions which by
                        any provision hereof are specifically required to be
                        furnished to the Trustee, the Trustee shall be under a
                        duty to examine the same to determine whether or not
                        they conform to the requirements of this Indenture;

            (2)   if any Event of Default has occurred and is continuing with
      respect to the Securities of any series, the Trustee shall exercise such
      of the rights and powers vested in it by this Indenture, and use the same
      degree of care and skill in their exercise, as a prudent person would
      exercise or use under the circumstances in the conduct of such person's
      own affairs;

            (3)   the Trustee may not be relieved from liabilities for its own
      negligent action, its own negligent failure to act, or its own willful
      misconduct, except that:

                  (a)   this subparagraph (3) does not limit the effect of
                        subparagraph (1) of this paragraph or the penultimate
                        paragraph of this Section 602;

                  (b)   the Trustee shall not be liable for any error of
                        judgment made in good faith by a Responsible Officer,
                        unless it is proved that the Trustee was negligent in
                        ascertaining the pertinent facts; and

                  (c)   the Trustee shall not be liable with respect to any
                        action taken or omitted to be taken by it in good faith
                        in accordance with the direction of the Holders of a
                        majority in principal amount of the

                                       49

<PAGE>

                        Outstanding Securities of the affected series relating
                        to the time, method and place of conducting any
                        proceeding for any remedy available to the Trustee, or
                        exercising any trust or power conferred upon the
                        Trustee, under this Indenture;

            (4)   the Trustee may conclusively rely and shall be fully protected
      in acting or refraining from acting upon any resolution, certificate,
      statement, instrument, opinion, report, notice, request, direction,
      consent, order, bond, debenture, note, other evidence of indebtedness or
      other paper or document believed by it to be genuine and to have been
      signed or presented by the proper party or parties;

            (5)   any request or direction of the Company mentioned herein shall
      be sufficiently evidenced by a Company Request or Company Order and any
      resolution of the Board of Directors may be sufficiently evidenced by a
      Board Resolution;

            (6)   whenever in the administration of this Indenture the Trustee
      shall deem it desirable that a matter be proved or established prior to
      taking, suffering or omitting any action hereunder, the Trustee (unless
      other evidence be herein specifically prescribed) may, in the absence of
      bad faith on its part, conclusively rely upon an Officer's Certificate;

            (7)   the Trustee may consult with counsel and the written advice of
      such counsel or any Opinion of Counsel shall be full and complete
      authorization and protection in respect of any action taken, suffered or
      omitted by it hereunder in good faith and in reliance thereon;

            (8)   the Trustee shall be under no obligation to exercise any of
      the rights or powers vested in it by this Indenture at the request or
      direction of any of the Holders of Securities of any series or any related
      coupons pursuant to this Indenture, unless such Holders shall have offered
      to the Trustee reasonable security or indemnity satisfactory to it against
      the costs, expenses and liabilities which might be incurred by it in
      compliance with such request or direction;

            (9)   the Trustee shall not be bound to make any investigation into
      the facts or matters stated in any resolution, certificate, statement,
      instrument, opinion, report, notice, request, direction, consent, order,
      bond, debenture, note, other evidence of indebtedness or other paper or
      document, but the Trustee, in its discretion, may make such further
      inquiry or investigation into such facts or matters as it may see fit,
      and, if the Trustee shall determine to make such further inquiry or
      investigation, it shall be entitled to examine the books, records and
      premises of the Company, personally or by agent or attorney;

            (10)  the Trustee may execute any of the trusts or powers hereunder
      or perform any duties hereunder either directly or by or through agents,
      attorneys, custodians, or nominees and the Trustee shall not be
      responsible for any misconduct or negligence on the part of any agent,
      attorney, custodian, or nominee appointed with due care by it hereunder;

                                       50

<PAGE>

            (11)  the Trustee shall not be liable for any action taken, suffered
      or omitted by it in good faith and believed by it to be authorized or
      within the discretion or rights or powers conferred upon it by this
      Indenture;

            (12)  in the event that the Trustee is also acting as Paying Agent,
      Security Registrar or in any other capacity hereunder, the rights,
      privileges, protections, immunities and benefits afforded to the Trustee
      pursuant to this Article Six, including, without limitation, its right to
      be indemnified, shall also be afforded to the Trustee in its capacity as
      such Paying Agent, Security Registrar or in such other capacity; and

            (13)  the Trustee shall not be deemed to know or be charged with
      knowledge of any Default or Event of Default with respect to the
      Securities of any series for which it is acting as Trustee unless a
      Responsible Officer of the Trustee shall have received written notice
      thereof at the Corporate Trust Office of the Trustee from the Company or a
      Holder of such Securities and such notice references this Indenture and
      such Securities.

            The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

            Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 602.

            SECTION 603. Trustee Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities, except for the
Trustee's certificates of authentication, and in any coupons shall be taken as
the statements of the Company, and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility on Form T-1 supplied to the Company are true and
accurate, subject to the qualifications set forth therein. Neither the Trustee
nor any Authenticating Agent shall be accountable for the use or application by
the Company of Securities or the proceeds thereof.

            SECTION 604. May Hold Securities. The Trustee, any Authenticating
Agent, any Paying Agent, any Security Registrar or any other agent of the
Company or of the Trustee, in its individual or any other capacity, may become
the owner or pledgee of Securities and coupons and, subject to TIA Sections
310(b) and 311, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

            SECTION 605. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The

                                       51

<PAGE>

Trustee shall be under no liability for interest on any money received by it
hereunder except as otherwise agreed with the Company or for the investment
thereof.

            SECTION 606. Compensation and Reimbursement. The Company agrees:

            (1)   to pay to the Trustee from time to time reasonable
      compensation for all services rendered by it hereunder (which compensation
      shall not be limited by any provision of law in regard to the compensation
      of a trustee of an express trust);

            (2)   except as otherwise expressly provided herein, to reimburse
      the Trustee upon its request for all reasonable expenses, disbursements
      and advances incurred or made by the Trustee in accordance with any
      provision of this Indenture (including the reasonable compensation and the
      expenses and disbursements of its agents and counsel), except any such
      expense, disbursement or advance as may be attributable to its gross
      negligence or willful misconduct; and

            (3)   to indemnify the Trustee and any predecessor trustee and its
      and their officers, directors, employees, and agents for, and to hold it
      or them harmless against, any loss, liability or expense incurred without
      gross negligence or willful misconduct on its or their part, arising out
      of or in connection with the acceptance or administration of the trust or
      trusts hereunder, including the costs and expenses (including reasonable
      fees and expenses of counsel) of defending itself or themselves against
      any claim or liability in connection with the exercise or performance of
      any of its or their powers or duties hereunder.

            The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture, the resignation or removal of the Trustee and the
termination of this Indenture for any reason. As security for the performance of
such obligations of the Company, the Trustee shall have a claim and lien prior
to the Securities upon all property and funds held or collected by the Trustee
as such, except funds held in trust for the payment of principal of (or premium,
if any) or interest, if any, on particular Securities or any coupons.

            When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(5) or (6), the expenses
(including reasonable charges and expense of its counsel) of and the
compensation for such services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

            The provisions of this Section shall survive the satisfaction and
discharge of this Indenture, the termination of this Indenture for any reason
and the earlier resignation or removal of the Trustee.

            SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests; Disqualification. There shall be at all times a Trustee hereunder
which shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall
have a combined capital and surplus of at least $50,000,000. If such corporation
publishes reports of condition at least annually, pursuant to law

                                       52

<PAGE>

or to the requirements of Federal, State, territorial or District of Columbia
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article. If the
Trustee shall have or acquire any conflicting interest within the meaning of the
Trust Indenture Act, it shall either eliminate such conflicting interest or
resign to the extent, in the manner and with the effect, and subject to the
conditions, provided in the Trust Indenture Act and this Indenture. For purposes
of Section 310(b)(1) of the Trust Indenture Act and to the extent permitted
thereby, the Trustee, in its capacity as trustee in respect of the Securities of
any series, shall not be deemed to have a conflicting interest arising from its
capacity as trustee in respect of the Securities of any other series or any
securities of any series issued under the Indenture, dated as of September 1,
1997, of the Company to The Chase Manhattan Bank, as trustee, pursuant to which
the Company's 65/8% Notes due 2005 were issued. Nothing contained herein shall
prevent the Trustee from filing the application provided for in the second to
last sentence of Section 310(b) of the Trust Indenture Act.

            SECTION 608. Resignation and Removal; Appointment of Successor. (a)
No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 609 and any and all amounts then due and owing to the
Trustee hereunder have been paid in full.

            (b)   The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 609 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

            (c)   The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series, delivered to the
Trustee and to the Company.

            (d)   If at any time:

            (1)   the Trustee shall fail to comply with the provisions of TIA
      Section 310(b) after written request therefor by the Company or by any
      Holder who has been a bona fide Holder of a Security for at least six
      months, or

            (2)   the Trustee shall cease to be eligible under Section 607 and
      shall fail to resign after written request therefor by the Company or by
      any Holder who has been a bona fide Holder of a Security for at least six
      months, or

            (3)   the Trustee shall become incapable of acting or shall be
      adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
      property shall be appointed or

                                       53

<PAGE>

      any public officer shall take charge or control of the Trustee or of its
      property or affairs for the purpose of rehabilitation, conservation or
      liquidation,

then, in any such case, (i) the Company, by a Board Resolution, may remove the
Trustee with respect to all Securities, or (ii) subject to TIA Section 315(e),
any Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

            (e)   If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series). If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment, become the successor Trustee with respect to the Securities
of such series and to that extent supersede the successor Trustee appointed by
the Company. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Security of such series for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

            (f)   The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to the Holders of Securities of such series in the manner provided for in
Section 106. Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

            SECTION 609. Acceptance of Appointment by Successor. In case of the
appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder, subject nevertheless to its claim and lien
provided for in Section 606.

                                       54

<PAGE>

            (a)   In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates, subject nevertheless to its claim and lien
provided for in Section 606. Whenever there is a successor Trustee with respect
to one or more (but less than all) series of securities issued pursuant to this
Indenture, the terms "Indenture" and "Securities" shall have the meanings
specified in the provisos to the respective definitions of those terms in
Section 101 which contemplate such situation.

            (b)   Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (a) or (b) of this Section, as the case may be.

            (c)   No successor Trustee shall accept its appointment unless at
the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article.

            SECTION 610. Merger, Conversion, Consolidation or Succession to
Business. Any Person into which the Trustee may be merged or converted or with
which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any Person
succeeding to all or substantially all the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such Person
shall be otherwise qualified and eligible under this Article, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such authentication and

                                       55

<PAGE>

deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities. In case any of the
Securities shall not have been authenticated by such predecessor Trustee, any
successor Trustee may authenticate such Securities either in the name of any
predecessor hereunder or in the name of the successor Trustee. In all such cases
such certificates shall have the full force and effect which this Indenture
provides for the certificate of authentication of the Trustee; provided,
however, that the right to adopt the certificate of authentication of any
predecessor Trustee or to authenticate Securities in the name of any predecessor
Trustee shall apply only to its successor or successors by merger, conversion or
consolidation.

            SECTION 611. Appointment of Authenticating Agent. At any time when
any of the Securities remain Outstanding, the Trustee may appoint an
Authenticating Agent or Agents with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities of such series and the Trustee shall give written notice of such
appointment to all Holders of Securities of the series with respect to which
such Authenticating Agent will serve, in the manner provided for in Section 106.
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Any such appointment shall be evidenced by an instrument in
writing signed by a Responsible Officer of the Trustee, and a copy of such
instrument shall be promptly furnished to the Company. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any state thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by federal or state authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect specified in this
Section.

            Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

            An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the

                                       56

<PAGE>

Company. Upon receiving such a notice of resignation or upon such a termination,
or in case at any time such Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the Company and
shall give written notice of such appointment to all Holders of Securities of
the series with respect to which such Authenticating Agent will serve, in the
manner provided for in Section 106. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

            The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 606.

            If an appointment with respect to one or more series is made
pursuant to this Section, the Securities of such series may have endorsed
thereon, in addition to the Trustee's certificate of authentication, an
alternate certificate of authentication in the following form:

            Dated: ____________________

            This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

            SECTION 701. Disclosure of Names and Addresses of Holders. Every
Holder of Securities or coupons, by receiving and holding the same, agrees with
the Company and the Trustee that none of the Company or the Trustee or any agent
of either of them shall be held accountable by reason of the disclosure of any
such information as to the names and addresses of the Holders in accordance with
TIA Section 312, regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under Section 312(b).

            SECTION 702. Reports by Trustee. Within 60 days after May 15 of each
year commencing with the first May 15 after the first issuance of Securities
pursuant to this Indenture, the Trustee shall transmit to the Holders of
Securities, in the manner and to the extent provided in TIA Section 313(c), a
brief report dated as of such May 15 if required by TIA Section 313(a). The
Company will promptly notify the Trustee when Securities are listed on any stock
exchange and of any delisting thereof.

            SECTION 703. Reports by Company. The Company shall:

            (1)   file with the Trustee, within 15 days after the Company is
      required to file the same with the Commission, copies of the annual
      reports and of the information, documents and other reports (or copies of
      such portions of any of the foregoing as the Commission may from time to
      time by rules and regulations prescribe) which the Company may be required
      to file with the Commission pursuant to Section 13 or Section 15(d) of the
      Securities Exchange Act of 1934; or, if the Company is not required to
      file information, documents or reports pursuant to either of such
      Sections, then it shall file with the Trustee and the Commission, in
      accordance with rules and regulations prescribed from time to time by the
      Commission, such of the supplementary and periodic information, documents
      and reports which may be required pursuant to Section 13 of the Securities
      Exchange Act of 1934 in respect of a security listed and registered on a
      national securities exchange as may be prescribed from time to time in
      such rules and regulations;

            (2)   file with the Trustee and the Commission, in accordance with
      rules and regulations prescribed from time to time by the Commission, such
      additional information, documents and reports with respect to compliance
      by the Company with the conditions and covenants of this Indenture as may
      be required from time to time by such rules and regulations; and

            (3)   transmit to all Holders, in the manner and to the extent
      provided in TIA Section 313(c), within 30 days after the filing thereof
      with the Trustee, such summaries of any information, documents and reports
      required to be filed by the Company pursuant to paragraphs (1) and (2) of
      this Section as may be required by rules and regulations prescribed from
      time to time by the Commission.

            Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officer's Certificates).

              CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

            SECTION 801. Company May Consolidate, etc., Only on Certain Terms.
The Company shall not consolidate with or merge into any other Person or
transfer all or substantially all of its property and assets as an entirety to
any Person, unless:

            (a)   either the Company shall be the continuing Person, or the
      Person (if other than the Company) formed by such consolidation or into
      which the Company is merged or to which all or substantially all of the
      properties and assets of the Company as an entirety are transferred is a
      Person organized and existing under the laws of the United States or any
      State thereof or the District of Columbia which expressly assumes all of
      the obligations of the Company under each series of Securities and this
      Indenture with respect to each such series by an indenture supplemental
      hereto, executed and delivered to the Trustee, in form satisfactory to the
      Trustee, the due and punctual payment of the principal of (and premium, if
      any) and interest on all the Securities and the performance of every

      observed;

            (b)   immediately before and immediately after giving effect to such
      transaction, no Event of Default and no Default shall have occurred and be

      with, merge with or into or transfer all or part of its properties and
      assets to the Company or any other Subsidiary or Subsidiaries; and

            (c)   the Company has delivered to the Trustee an Officer's
      Certificate and an Opinion of Counsel each stating that such

merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, and be
subject to every obligation of, the Company under this Indenture with the same
effect as if such successor Person had been named as the Company herein, and in
the event of any such conveyance or transfer, the Company (which term shall for
this purpose mean the Person named as the "Company" in the first paragraph of
this Indenture or any successor Person which shall theretofore become such in
the manner described in Section 801), except in the case of a lease, shall be
discharged of all obligations and covenants under this Indenture and the
Securities and the coupons and may be dissolved and liquidated.

                             SUPPLEMENTAL INDENTURES

            SECTION 901. Supplemental Indentures Without Consent of Holders.
Without the consent of any Holders, the Company, when authorized by or pursuant
to a Board Resolution, and the Trustee, at any time and from time to time, may
enter into one or more indentures supplemental hereto, in form satisfactory to
the Trustee, for any of the following purposes:

            (1)   to evidence the succession of another Person to the Company
      and the assumption by any such successor of the covenants of the Company
      contained herein and in the Securities; or

            (2)   to add to the covenants of the Company for the benefit of the
      Holders of all or any series of Securities and any related coupons (and if
      such covenants are to be for the benefit of less than all series of
      Securities, stating that such covenants are being included solely for the
      benefit of such series) or to surrender any right or power herein
      conferred upon the Company; or

            (3)   to add any additional Events of Default (and if such Events of
      Default are to be for the benefit of less than all series of Securities,
      stating that such Events of Default are being included solely for the
      benefit of such series); or

            (4)   to add to or change any of the provisions of this Indenture to

      adversely affect the interests of the Holders of Securities of any series
      or any related coupons in any material respect; or

            (5)   to change or eliminate any of the provisions of this
      Indenture; provided that any such change or elimination shall become
      effective only when there is no Security Outstanding of any series created

      the benefit of such provision; or

            (6)   to secure the Securities pursuant to the requirements of
      Section 1009 or otherwise; or

            (7)   to establish the form or terms of Securities of any series as

      facilitate the administration of the trusts hereunder by more than one
      Trustee, pursuant to the requirements of Section 609(b); or

      delivery of additional series of Securities, to cure any ambiguity, to
      correct or supplement any provision herein which may be inconsistent with
      any other provision herein, or to make any other provisions with respect
      to matters or questions arising under this Indenture; provided such action
      shall not adversely affect the interests of the Holders of Securities of
      any series and any related coupons in any material respect; or

            (10)  to supplement any of the provisions of this Indenture to such
      extent as shall be necessary to permit or facilitate the defeasance and
      discharge of any series of Securities pursuant to Sections 401, 1402 and
      1403; provided that any such action shall not adversely affect the
      interests of the Holders of Securities of such series and any related
      coupons or any other series of Securities in any material respect.

            SECTION 902. Supplemental Indentures with Consent of Holders. With
the consent of the Holders of not less than a majority in principal amount of
all Outstanding Securities affected by such supplemental indenture, by Act of
said Holders delivered to the Company and the Trustee, the Company, when
authorized by or pursuant to a Board Resolution, and the Trustee may enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture which affect such series of Securities or of modifying in any
manner the rights of the Holders of Securities of such series under this
Indenture; provided, however, that no such supplemental indenture shall, without
the consent of the Holder of each Outstanding Security affected thereby,

            (1)   change the Stated Maturity of the principal of (or premium, if
      any) or any installment of interest on any Security of such series, or
      reduce the principal amount thereof (or premium, if any) or the rate of
      interest, if any, thereon, or change any obligation of the Company to pay
      Additional Amounts contemplated by Section 1005 (except as contemplated by
      Section 801(1) and permitted by Section 901(1)), or reduce the amount of
      the principal of an Original Issue Discount Security of such series that
      would be due and payable upon a declaration of acceleration of the
      Maturity thereof pursuant to Section 502 or the amount thereof provable in
      bankruptcy pursuant to Section 504, or adversely affect any right of
      repayment at the option of any Holder of any Security of such series, or
      change any Place of Payment where, or the Currency in which, any Security
      of such series or any premium or interest thereon is payable, or impair
      the right to institute suit for the enforcement of any such payment on or
      after the Stated Maturity thereof (or, in the case of redemption or
      repayment at the option of the Holder, on or after the Redemption Date or
      Repayment Date, as the case may be), or adversely affect any right to
      convert or exchange any Security as may be provided pursuant to Section
      301 herein, or

            (2)   reduce the percentage in principal amount of the Outstanding
      Securities of any series, the consent of whose Holders is required for any
      such supplemental indenture, for any waiver of compliance with certain
      provisions of this Indenture which affect such

                                       61

<PAGE>

      series or certain defaults applicable to such series hereunder and their
      consequences provided for in this Indenture, or reduce the requirements of
      Section 1504 for quorum or voting with respect to Securities of such
      series, or

            (3)   modify any of the provisions of this Section, Section 513 or
      Section 1011, except to increase any such percentage or to provide that
      certain other provisions of this Indenture which affect such series cannot
      be modified or waived without the consent of the Holder of each
      Outstanding Security affected thereby.

            It shall not be necessary for any Act of Holders under this Section
to approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

            SECTION 903. Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

            SECTION 904. Effect of Supplemental Indentures. Upon the execution
of any supplemental indenture under this Article, this Indenture shall be

theretofore or thereafter authenticated and delivered hereunder shall be bound
thereby.

Securities of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

            SECTION 907. Notice of Supplemental Indentures. Promptly after the
execution by the Company and the Trustee of any supplemental indenture pursuant
to the provisions of Section 902, the Company shall give notice thereof to the
Holders of each Outstanding Security affected, in the manner provided for in
Section 106, setting forth in general terms the substance of such supplemental
indenture.

under Article Sixteen without the consent of such holder.

                                   ARTICLE TEN

                                    COVENANTS

            SECTION 1001. Payment of Principal, Premium, if any, and Interest.
The Company covenants and agrees for the benefit of the Holders of each series
of Securities and any related coupons that it will duly and punctually pay the
principal of (and premium, if any) and interest, if any, on the Securities of
that series in accordance with the terms of the Securities, any coupons
appertaining thereto and this Indenture. Unless otherwise specified as
contemplated by Section 301 with respect to any series of Securities, any
interest installments due on Bearer Securities on or before Maturity shall be
payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature.

            SECTION 1002. Maintenance of Office or Agency. If the Securities of
a series are issuable only as Registered Securities, the Company will maintain
in each Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or
exchange, where Securities of that series that are convertible or exchangeable
may be surrendered for conversion or exchange, as applicable and where notices
and demands to or upon the Company in respect of the Securities of that series
and this Indenture may be served.

            If Securities of a series are issuable as Bearer Securities, the
Company will maintain (A) in The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where Securities of that series that are convertible or exchangeable
may be surrendered for conversion or exchange, as applicable, where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served and where Bearer Securities of that series and
related coupons may be presented or surrendered for payment in the circumstances
described in the following paragraph (and not otherwise) (B) subject to any laws
or regulations applicable thereto, in a Place of Payment for that series which
is located outside the United States, an office or agency where Securities of
that series and related coupons may be presented and surrendered for payment;
provided, however, that, if the Securities of that series are listed on any
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Securities of that
series in any required city located outside the United States so long as the
Securities of that series are listed on such exchange, and (C) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
located outside the United States an office or agency where any Registered
Securities of that series may be surrendered for registration of transfer, where
Securities of that series may be surrendered for exchange, where Securities of
that series that are convertible and exchangeable may be surrendered for
conversion

                                       63

<PAGE>

or exchange, as applicable and where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served.

            The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, except that Bearer Securities of any series and the
related coupons may be presented and surrendered for payment at the offices
specified in the Security, in London, and the Company hereby appoints the same
as its agents to receive such respective presentations, surrenders, notices and
demands.

            Unless otherwise specified with respect to any Securities pursuant
to Section 301, no payment of principal, premium or interest on Bearer
Securities shall be made at any office or agency of the Company in the United
States or by check mailed to any address in the United States or by transfer to
an account maintained with a bank located in the United States; provided,
however, that, if the Securities of a series are payable in Dollars, payment of
principal of (and premium, if any) and interest, if any, on any Bearer Security
shall be made at the office of the Company's Paying Agent in The City of New
York, if (but only if) payment in Dollars of the full amount of such principal,
premium or interest, as the case may be, at all offices or agencies outside the
United States maintained for such purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

            The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
any such designation; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency. Unless otherwise specified with respect to
any Securities as contemplated by Section 301 with respect to a series of
Securities, the Company hereby designates as a Place of Payment for each series
of Securities the office or agency of the Trustee in the Borough of Manhattan,
The City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

            Unless otherwise specified with respect to any Securities pursuant
to Section 301, if and so long as the Securities of any series (i) are
denominated in a Currency other than Dollars or (ii) may be payable in a
Currency other than Dollars, or so long as it is required under any other
provision of the Indenture, then the Company will maintain with respect to each
such series of Securities, or as so required, at least one Exchange Rate Agent.

            SECTION 1003. Money for Securities Payments to Be Held in Trust. If
the Company shall at any time act as its own Paying Agent with respect to any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (or premium, if any) or interest, if any, on any of the
Securities of that series, segregate and hold in trust for the

                                       64

<PAGE>

benefit of the Persons entitled thereto a sum in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the principal
of (or premium, if any) or interest, if any, on Securities of such series so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

            Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, prior to or on each due
date of the principal of (or premium, if any) or interest, if any, on any
Securities of that series, deposit with a Paying Agent a sum (in the Currency
described in the preceding paragraph) sufficient to pay the principal (or
premium, if any) or interest, if any, so becoming due, such sum to be held in
trust for the benefit of the Persons entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act.

            The Company will cause each Paying Agent (other than the Trustee)
for any series of Securities to execute and deliver to the Trustee an instrument
in which such Paying Agent shall agree with the Trustee, subject to the
provisions of this Section, that such Paying Agent will:

            (1)   hold all sums held by it for the payment of the principal of
      (and premium, if any) and interest, if any, on Securities of such series
      in trust for the benefit of the Persons entitled thereto until such sums
      shall be paid to such Persons or otherwise disposed of as herein provided;

            (2)   give the Trustee notice of any default by the Company (or any
      other obligor upon the Securities of such series) in the making of any
      payment of principal of (or premium, if any) or interest, if any, on the
      Securities of such series; and

            (3)   at any time during the continuance of any such default, upon
      the written request of the Trustee, forthwith pay to the Trustee all sums
      so held in trust by such Paying Agent.

            The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
sums.

            Except as provided in the Securities of any series, and subject to
any applicable abandoned property laws, any money deposited with the Trustee or
any Paying Agent, or then held by the Company, in trust for the payment of the
principal of (or premium, if any) or interest, if any, on any Security of any
series, or any coupon appertaining thereto, and remaining unclaimed for two
years after such principal, premium or interest has become due and payable shall
be paid to the Company on Company Request, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Security or coupon
shall thereafter, as an

                                       65

<PAGE>

unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in an Authorized Newspaper, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

            SECTION 1004. Statement as to Compliance. The Company will deliver
to the Trustee, within 120 days after the end of each fiscal year, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer as to his or her knowledge of the Company's
compliance with all conditions and covenants under this Indenture. For purposes
of this Section 1004, such compliance shall be determined without regard to any
period of grace or requirement of notice under this Indenture.

            SECTION 1005. Additional Amounts. If any Securities of a series
provide for the payment of additional amounts to any Holder who is not a United
States person in respect of any tax, assessment or governmental charge
("Additional Amounts"), the Company will pay to the Holder of any Security of
such series or any coupon appertaining thereto such Additional Amounts as may be
specified as contemplated by Section 301. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal (or premium, if any) or
interest, if any, on, or in respect of, any Security of a series or payment of
any related coupon or the net proceeds received on the sale or exchange of any
Security of a series, such mention shall be deemed to include mention of the
payment of Additional Amounts provided for by the terms of such series
established pursuant to Section 301 to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof pursuant to
such terms and express mention of the payment of Additional Amounts (if
applicable) in any provisions hereof shall not be construed as excluding
Additional Amounts in those provisions hereof where such express mention is not
made.

            Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal (and premium, if any) is
made), and at least 10 days prior to each date of payment of principal (or
premium, if any) or interest if there has been any change with respect to the
matters set forth in the below-mentioned Officer's Certificate, the Company will
furnish the Trustee and the Company's principal Paying Agent or Paying Agents,
if other than the Trustee, with an Officer's Certificate instructing the Trustee
and such Paying Agent or Paying Agents whether such payment of principal,
premium or interest on the Securities of that series shall be made to Holders of
Securities of that series or any related coupons who are not United States
persons without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of the series. If any such
withholding shall be required, then such Officer's Certificate shall specify by
country the amount, if any, required to be withheld on such payments to such
Holders of Securities of that series or related coupons and the Company will pay
to the Trustee or such Paying Agent the Additional Amounts required by the terms
of such Securities.

                                       66

<PAGE>

In the event that the Trustee or any Paying Agent, as the case may be, shall not
so receive the above-mentioned certificate, then the Trustee or such Paying
Agent shall be entitled to (i) assume that no such withholding or deduction is
required with respect to any payment of principal of (or premium, if any) or
interest, if any, on any Securities of a series or related coupons until it
shall have received a certificate advising otherwise and (ii) to make all
payments of principal of (and premium, if any) and interest, if any, on the
Securities of a series or related coupons without withholding or deductions
until otherwise advised. The Company covenants to indemnify the Trustee, any
Paying Agent, and their respective officers, directors, employees, and agents
for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of
or in connection with actions taken or omitted by any of them in reliance on any
Officer's Certificate furnished pursuant to this Section. This sentence shall
survive the termination of this Indenture and the earlier resignation or removal
of the Trustee.

            SECTION 1006. Payment of Taxes and Other Claims. The Company will
pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all material taxes, assessments and governmental charges levied
or imposed upon the Company or any Restricted Subsidiary or upon the income,
profits or property of the Company or any Restricted Subsidiary, and (2) all
material lawful claims for labor, materials and supplies which, if unpaid, might
by law become a Lien upon any Principal Property of the Company or any
Restricted Subsidiary; provided, however, that the Company shall not be required
to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings.

            SECTION 1007. Maintenance of Principal Properties. The Company will
cause all Principal Properties to be maintained and kept in good condition,
repair and working order and supplied with all necessary equipment and will
cause to be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
Section shall prevent or restrict the sale, abandonment or other disposition of
any of such Principal Properties if such action is, in the judgment of the
Company, desirable in the conduct of the business (financial or otherwise) of
the Company and its Subsidiaries as a whole and not disadvantageous in any
material respect to the Holders.

            SECTION 1008. Corporate Existence. Subject to Article Eight, the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence and the rights (charter and
statutory) and franchises of the Company and any Restricted Subsidiary;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Company shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Company and its
Subsidiaries as a whole.

            SECTION 1009. Limitation on Liens. The Company shall not, and shall
not permit any of its Subsidiaries to, directly or indirectly, create, incur,
assume or suffer to exist any Lien upon any of its property, assets or revenues,
whether now owned or hereafter acquired, except for:

                                       67

<PAGE>

            (a)   Liens for taxes not yet due or which are being contested in
      good faith by appropriate proceedings, provided that adequate reserves
      with respect thereto are maintained on the books of the Company or its
      Subsidiaries, as the case may be, in conformity with GAAP;

            (b)   carriers', warehousemen's, mechanics', materialmen's,
      repairmen's or other like Liens arising in the ordinary course of business
      which are not overdue for a period of more than 60 days or which are being
      contested in good faith by appropriate proceedings;

            (c)   pledges or deposits in connection with workers' compensation,
      unemployment insurance and other social security legislation and deposits
      securing liability to insurance carriers under insurance or self-insurance
      arrangements;

            (d)   deposits to secure the performance of bids, trade contracts
      (other than for borrowed money), leases, statutory obligations, surety and
      appeal bonds, performance bonds and other obligations of a like nature
      incurred in the ordinary course of business;

            (e)   easements, rights-of-way, restrictions and other similar
      encumbrances incurred in the ordinary course of business which, in the
      aggregate, are not substantial in amount and which do not in any case
      materially detract from the value of the property subject thereto or
      materially interfere with the ordinary conduct of the business of the
      Company or such Subsidiary;

            (f)   Liens in existence on the date of the first issuance by the
      Company of Securities issued pursuant to this Indenture; provided that no
      such Lien is spread to cover any additional property after such date and
      that the amount of Debt secured thereby is not increased;

            (g)   Liens securing Debt of the Company and its Subsidiaries
      incurred to finance the acquisition of fixed or capital assets; provided
      that (i) such Liens shall be created substantially simultaneously with the
      acquisition of such fixed or capital assets, (ii) such Liens do not at any
      time encumber any property other than the property financed by such Debt
      and (iii) the amount of Debt secured thereby is not increased;

            (h)   Liens on the property or assets of a corporation which becomes
      a Subsidiary after the date hereof; provided that (i) such Liens existed
      at the time such corporation became a Subsidiary and were not created in
      anticipation thereof, (ii) any such Lien is not spread to cover any
      property or assets or such corporation after the time such corporation
      becomes a Subsidiary, and (iii) the amount of Debt secured thereby is not
      increased;

            (i)   Liens pursuant to any Receivables Transaction in an aggregate
      principal amount not to exceeding 20% of Consolidated Tangible Assets; and

            (j)   Liens (not otherwise permitted hereunder) (i) which secure
      obligations not exceeding (as to the Company and all Subsidiaries) the
      greater of (x) $100,000,000 or (y) 20% of Consolidated Net Worth, in each
      case in aggregate amount at any time

                                       68

<PAGE>

      outstanding or (ii) with respect to which the Company effectively provides
      that the Securities Outstanding hereunder are secured equally and ratably
      with (or, at the option of the Company, prior to) the Debt secured by such
      Lien.

            SECTION 1010. Waiver of Certain Covenants. The Company may, with
respect to any series of Securities, omit in any particular instance to comply
with any term, provision or condition which affects such series set forth in
Sections 1006 to 1010, inclusive, or, as specified pursuant to Section 301(15)
for Securities of such series, in any covenants of the Company added to Article
Ten pursuant to Section 301(14) or Section 301(15) in connection with Securities
of such series, if the Holders of at least a majority in principal amount of all
Outstanding Securities affected by such term, provision or condition, by Act of
such Holders, waive such compliance in such instance with such term, provision
or condition, but no such waiver shall extend to or affect such term, provision
or condition except to the extent so expressly waived, and, until such waiver
shall become effective, the obligations of the Company and the duties of the
Trustee to Holders of Securities of such series in respect of any such term,
provision or condition shall remain in full force and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

            SECTION 1101. Applicability of Article. Securities of any series
which are redeemable before their Stated Maturity shall be redeemable in
accordance with the terms of such Securities and (except as otherwise specified
as contemplated by Section 301 for Securities of any series) in accordance with
this Article.

            SECTION 1102. Election to Redeem; Notice to Trustee. The election of
the Company to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution. In case of any redemption at the election of the Company, the
Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed and shall deliver to the Trustee such documentation
and records as shall enable the Trustee to select the Securities to be redeemed
pursuant to Section 1103. In the case of any redemption of Securities prior to
the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officer's Certificate evidencing compliance with such
restriction.

            SECTION 1103. Selection by Trustee of Securities to Be Redeemed. If
less than all the Securities of any series are to be redeemed, the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
portions of the principal of Securities of such series; provided, however, that
no such partial redemption shall reduce the portion of the principal amount of a
Security not redeemed to less than the minimum authorized denomination for
Securities of such series established pursuant to Section 301.

                                       69

<PAGE>

            The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

            For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

            SECTION 1104. Notice of Redemption. Except as otherwise specified as
contemplated by Section 301 for Securities of any series, notice of redemption
shall be given in the manner provided for in Section 106 not less than 30 nor
more than 60 days prior to the Redemption Date, to each Holder of Securities to
be redeemed.

            Except as otherwise specified as contemplated by Section 301 for
Securities of any series, all notices of redemption shall state:

            (1)   the Redemption Date,

            (2)   the Redemption Price (if known) or the formula pursuant to
      which the Redemption Price is to be determined if the Redemption Price
      cannot be determined at the time the notice is given,

            (3)   if less than all the Outstanding Securities of any series are
      to be redeemed, the identification (and, in the case of partial
      redemption, the principal amounts) of the particular Securities to be
      redeemed,

            (4)   in case any Security is to be redeemed in part only, the
      notice which relates to such Security shall state that on and after the
      Redemption Date, upon surrender of such Security, the holder will receive,
      without charge, a new Security or Securities of authorized denominations
      for the principal amount thereof remaining unredeemed,

            (5)   that on the Redemption Date, the Redemption Price and accrued
      interest, if any, to the Redemption Date payable as provided in Section
      1106 will become due and payable upon each such Security, or the portion
      thereof, to be redeemed and, if applicable, that interest thereon will
      cease to accrue on and after said date,

            (6)   the Place or Places of Payment where such Securities, together
      in the case of Bearer Securities with all coupons appertaining thereto, if
      any, maturing after the Redemption Date, are to be surrendered for payment
      of the Redemption Price and accrued interest, if any,

            (7)   that the redemption is for a sinking fund, if such is the
      case,

            (8)   that, unless otherwise specified in such notice, Bearer
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all coupons maturing subsequent to the Redemption Date or
      the amount of any such missing coupon or

                                       70

<PAGE>

      coupons will be deducted from the Redemption Price unless security or
      indemnity satisfactory to the Company, the Trustee and any Paying Agent is
      furnished,

            (9)   if Bearer Securities of any series are to be redeemed and any
      Registered Securities of such series are not to be redeemed, and if such
      Bearer Securities may be exchanged for Registered Securities not subject
      to redemption on such Redemption Date pursuant to Section 305 or
      otherwise, the last date, as determined by the Company, on which such
      exchanges may be made,

            (10)  the CUSIP, ISIN or other similar numbers, if any, assigned to
      such Securities; provided, however, that such notice may state that no
      representation is made as to the correctness of CUSIP, ISIN or other
      similar numbers, in which case none of the Company, the Trustee or any
      agent of the Company or the Trustee shall have any liability in respect of
      the use of any CUSIP, ISIN or other similar number or numbers on such
      notices, and the redemption of such Securities shall not be affected by
      any defect in or omission of such numbers, and

            (11)  such other matters as the Company shall deem desirable or
      appropriate.

            Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

            SECTION 1105. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money in the Currency in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if
applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay
the Redemption Price of, and accrued interest, if any, on, all the Securities
which are to be redeemed on that date.

            SECTION 1106. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified in the Currency in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series and except, if applicable, as provided in Sections
312(b), 312(d) and 312(e)) (together with accrued interest, if any, to the
Redemption Date), and from and after such date (unless the Company shall default
in the payment of the Redemption Price and accrued interest, if any) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void. Upon surrender of
any such Security for redemption in accordance with said notice, together with
all coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated

                                       71

<PAGE>

by Section 301, only upon presentation and surrender of coupons for such
interest; and provided further that installments of interest on Registered
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

            If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

            If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) set forth
in such Security.

            SECTION 1107. Securities Redeemed in Part. Any Security which is to
be redeemed only in part (pursuant to the provisions of this Article or of
Article Twelve) shall be surrendered at a Place of Payment therefor (with, if
the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly
executed by, the Holder thereof or such Holder's attorney duly authorized in
writing), and the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder of such Security without service charge, a new Security or
Securities of the same series, of any authorized denomination as requested by
such Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

            SECTION 1201. Applicability of Article. Retirements of Securities of
any series pursuant to any sinking fund shall be made in accordance with the
terms of such Securities and (except as otherwise specified as contemplated by
Section 301 for Securities of any series) in accordance with this Article.

            The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any

                                       72

<PAGE>

payment in excess of such minimum amount provided for by the terms of Securities
of any series is herein referred to as an "optional sinking fund payment". If
provided for by the terms of Securities of any series, the cash amount of any
mandatory sinking fund payment may be subject to reduction as provided in
Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

            SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.
Subject to Section 1203, in lieu of making all or any part of any mandatory
sinking fund payment with respect to any Securities of a series in cash, the
Company may at its option (1) deliver to the Trustee Outstanding Securities of a
series (other than any previously called for redemption) theretofore purchased
or otherwise acquired by the Company, together, in the case of any Bearer
Securities of such series, with all unmatured coupons appertaining thereto,
and/or (2) receive credit for the principal amount of Securities of such series
which have been previously delivered to the Trustee by the Company or for
Securities of such series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any mandatory
sinking fund payment with respect to the Securities of the same series required
to be made pursuant to the terms of such Securities as provided for by the terms
of such series; provided, however, that such Securities have not been previously
so credited. Such Securities shall be received and credited for such purpose by
the Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such mandatory sinking
fund payment shall be reduced accordingly.

            SECTION 1203. Redemption of Securities for Sinking Fund. Not less
than 60 days prior to each sinking fund payment date for any series of
Securities, the Company will deliver to the Trustee an Officer's Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash in the Currency in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 301 for
the Securities of such series and except, if applicable, as provided in Sections
312(b), 312(d) and 312(e)) and the portion thereof, if any, which is to be
satisfied by delivering or crediting Securities of that series pursuant to
Section 1202 (which Securities will, if not previously delivered, accompany such
certificate) and whether the Company intends to exercise its right to make a
permitted optional sinking fund payment with respect to such series. Such
certificate shall be irrevocable and upon its delivery the Company shall be
obligated to make the cash payment or payments therein referred to, if any, on
or before the next succeeding sinking fund payment date. In the case of the
failure of the Company to deliver such certificate, the sinking fund payment due
on the next succeeding sinking fund payment date for that series shall be paid
entirely in cash and shall be sufficient to redeem the principal amount of such
Securities subject to a mandatory sinking fund payment without the option to
deliver or credit Securities as provided in Section 1202 and without the right
to make any optional sinking fund payment, if any, with respect to such series.

            Not more than 60 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having

                                       73

<PAGE>

been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1106 and 1107.

            Prior to any sinking fund payment date, the Company shall pay to the
Trustee or a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) in cash a sum equal to
the principal (and premium, if any) and any interest that will accrue to the
date fixed for redemption of Securities or portions thereof to be redeemed on
such sinking fund payment date pursuant to this Section 1203.

            Notwithstanding the foregoing, with respect to a sinking fund for
any series of Securities, if at any time the amount of cash to be paid into such
sinking fund on the next succeeding sinking fund payment date, together with any
unused balance of any preceding sinking fund payment or payments for such
series, does not exceed in the aggregate $100,000, the Trustee, unless requested
by the Company, shall not give the next succeeding notice of the redemption of
Securities of such series through the operation of the sinking fund. Any such
unused balance of moneys deposited in such sinking fund shall be added to the
sinking fund payment for such series to be made in cash on the next succeeding
sinking fund payment date or, at the request of the Company, shall be applied at
any time or from time to time to the purchase of Securities of such series, by
public or private purchase, in the open market or otherwise, at a purchase price
for such Securities (excluding accrued interest and brokerage commissions, for
which the Trustee or any Paying Agent will be reimbursed by the Company) not in
excess of the principal amount thereof.

                                ARTICLE THIRTEEN

                         REPAYMENT AT OPTION OF HOLDERS

            SECTION 1301. Applicability of Article. Repayment of Securities of
any series before their Stated Maturity at the option of Holders thereof shall
be made in accordance with the terms of such Securities and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.

            SECTION 1302. Repayment of Securities. Securities of any series
subject to repayment in whole or in part at the option of the Holders thereof
will, unless otherwise provided in the terms of such Securities, be repaid at a
price equal to the principal amount thereof, together with interest, if any,
thereon accrued to the Repayment Date specified in or pursuant to the terms of
such Securities. The Company covenants that on or before the Repayment Date it
will deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in the Currency in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 301 for
the Securities of such series and except, if applicable, as provided in Sections
312(b), 312(d) and 312(e)) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of
and (except if the Repayment Date shall be an Interest Payment Date) accrued
interest, if any, on, all the Securities or portions thereof, as the case may
be, to be repaid on such date.

                                       74

<PAGE>

            SECTION 1303. Exercise of Option. Securities of any series subject
to repayment at the option of the Holders thereof will contain an "Option to
Elect Repayment" form on the reverse of such Securities. To be repaid at the
option of the Holder, any Security so providing for such repayment, with the
"Option to Elect Repayment" form on the reverse of such Security duly completed
by the Holder (or by the Holder's attorney duly authorized in writing), must be
received by the Company at the Place of Payment therefor specified in the terms
of such Security (or at such other place or places or which the Company shall
from time to time notify the Holders of such Securities) not earlier than 45
days nor later than 30 days prior to the Repayment Date. If less than the entire
principal amount of such Security is to be repaid in accordance with the terms
of such Security, the principal amount of such Security to be repaid, in
increments of the minimum denomination for Securities of such series, and the
denomination or denominations of the Security or Securities to be issued to the
Holder for the portion of the principal amount of such Security surrendered that
is not to be repaid, must be specified. The principal amount of any Security
providing for repayment at the option of the Holder thereof may not be repaid in
part if, following such repayment, the unpaid principal amount of such Security
would be less than the minimum authorized denomination of Securities of the
series of which such Security to be repaid is a part. Except as otherwise may be
provided by the terms of any Security providing for repayment at the option of
the Holder thereof, exercise of the repayment option by the Holder shall be
irrevocable unless waived by the Company.

            SECTION 1304. When Securities Presented for Repayment Become Due and
Payable. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable to the Holders of such Securities,
or one or more Predecessor Securities, registered as such at the close of
business on the relevant Record Dates according to their terms and the
provisions of Section 307.

            If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If

                                       75

<PAGE>

thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; provided, however, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

            If the principal amount of any Security surrendered for repayment
shall not be so repaid upon surrender thereof, such principal amount (together
with interest, if any, thereon accrued to such Repayment Date) shall, until
paid, bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

            SECTION 1305. Securities Repaid in Part. Upon surrender of any
Registered Security which is to be repaid in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge and at the expense of the Company, a new
Registered Security or Securities of the same series, of any authorized
denomination specified by the Holder, in an aggregate principal amount equal to
and in exchange for the portion of the principal of such Security so surrendered
which is not to be repaid.

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

            SECTION 1401. Company's Option to Effect Defeasance or Covenant
Defeasance. Except as otherwise specified as contemplated by Section 301 for
Securities of any series, the provisions of this Article Fourteen shall apply to
each series of Securities, and the Company may, at its option, effect defeasance
of the Securities of or within a series under Section 1402, or covenant
defeasance of or within a series under Section 1403 in accordance with the terms
of such Securities and in accordance with this Article.

            SECTION 1402. Defeasance and Discharge. Upon the Company's exercise
of the above option applicable to this Section with respect to any Securities of
or within a series, the Company shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities and any related coupons
on the date the conditions set forth in Section 1404 are satisfied (hereinafter,
"defeasance"). For this purpose, such defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by such
Outstanding Securities and any related coupons, which shall thereafter be deemed
to be "Outstanding" only for the purposes of Section 1405 and the other Sections
of this Indenture referred to in (A) and (B) below, and to have satisfied all
its other obligations under such Securities and any related coupons and this
Indenture insofar as such Securities and any related coupons are concerned (and
the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder: (A) the rights of Holders of such
Outstanding Securities and any related coupons to receive, solely from the trust
fund described in Section

                                       76

<PAGE>

1404 and as more fully set forth in such Section, payments in respect of the
principal of (and premium, if any) and interest, if any, on such Securities and
any related coupons when such payments are due, (B) the Company's obligations
with respect to such Securities under Sections 304, 305, 306, 1002 and 1003 and
with respect to the payment of Additional Amounts, if any, on such Securities as
contemplated by Section 1005, (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder including, without limitation, Section 606,
the last sentence of Section 1005, and the penultimate paragraph of Section 1405
and (D) this Article Fourteen. Subject to compliance with this Article Fourteen,
the Company may exercise its option under this Section 1402 notwithstanding the
prior exercise of its option under Section 1403 with respect to such Securities
and any related coupons.

            SECTION 1403. Covenant Defeasance. Upon the Company's exercise of
the above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be released from its obligations under
Sections 801 and 802 and Sections 1006 through 1010, and, if specified pursuant
to Section 301, its obligations under any other covenant, with respect to such
Outstanding Securities and any related coupons on and after the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any related coupons shall thereafter be
deemed not to be "Outstanding" for the purposes of any direction, waiver,
consent or declaration or Act of Holders (and the consequences of any thereof)
in connection with such covenants, but shall continue to be deemed "Outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to such Outstanding Securities and any related coupons,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of reference in any such covenant to any other provision
herein or in any other document and such omission to comply shall not constitute
a Default or an Event of Default under Section 501(4) or Section 501(8) or
otherwise, as the case may be, but, except as specified above, the remainder of
this Indenture and such Securities and any related coupons shall be unaffected
thereby.

            SECTION 1404. Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions to application of either Section 1402 or
Section 1403 to any Outstanding Securities of or within a series and any related
coupons:

            (1)   The Company shall irrevocably have deposited or caused to be
      deposited with the Trustee (or another trustee satisfying the requirements
      of Section 607 who shall agree to comply with the provisions of this
      Article Fourteen applicable to it) as trust funds in trust for the purpose
      of making the following payments, specifically pledged as security for,
      and dedicated solely to, the benefit of the Holders of such Securities and
      any related coupons, (A) an amount (in such Currency in which such
      Securities and any related coupons are then specified as payable at Stated
      Maturity), or (B) Government Obligations applicable to such Securities
      (determined on the basis of the Currency in which such Securities are then
      specified as payable at Stated Maturity) which through the scheduled
      payment of principal and interest in respect thereof in accordance with
      their terms will provide, not later than one day before the due date of
      any payment of principal of and premium, if any, and interest, if any,
      under such Securities and any related coupons, money in an amount, or (C)
      a combination thereof, sufficient, in the opinion of

                                       77

<PAGE>

      a nationally recognized firm of independent public accountants expressed
      in a written certification thereof delivered to the Trustee, to pay and
      discharge, and which shall be applied by the Trustee (or other qualifying
      trustee) to pay and discharge, (i) the principal of (and premium, if any)
      and interest, if any, on such Outstanding Securities and any related
      coupons on the Stated Maturity (or Redemption Date, if applicable) of such
      principal (and premium, if any) or installment of interest, if any, and
      (ii) any mandatory sinking fund payments or analogous payments applicable
      to such Outstanding Securities and any related coupons on the day on which
      such payments are due and payable in accordance with the terms of this
      Indenture and of such Securities and any related coupons; provided that
      the Trustee shall have been irrevocably instructed to apply such money or
      the proceeds of such Government Obligations to said payments with respect
      to such Securities and any related coupons. Before such a deposit, the
      Company may give to the Trustee, in accordance with Section 1102 hereof, a
      notice of its election to redeem all or any portion of such Outstanding
      Securities at a future date in accordance with the terms of the Securities
      of such series and Article Eleven hereof, which notice shall be
      irrevocable. Such irrevocable redemption notice, if given, shall be given
      effect in applying the foregoing.

            (2)   No Default or Event of Default with respect to such Securities
      or any related coupons shall have occurred and be continuing on the date
      of such deposit or, insofar as paragraphs (5) and (6) of Section 501 are
      concerned, at any time during the period ending on the 91st day after the
      date of such deposit (it being understood that this condition shall not be
      deemed satisfied until the expiration of such period).

            (3)   Such defeasance or covenant defeasance shall not result in a
      breach or violation of, or constitute a default under, this Indenture or
      any other material agreement or instrument to which the Company is a party
      or by which it is bound.

            (4)   In the case of an election under Section 1402, the Company
      shall have delivered to the Trustee an Opinion of Counsel stating that (x)
      the Company has received from, or there has been published by, the
      Internal Revenue Service a ruling, or (y) since the date of execution of
      this Indenture, there has been a change in the applicable federal income
      tax law, in either case to the effect that, and based thereon such opinion
      shall confirm that, the Holders of such Outstanding Securities and any
      related coupons will not recognize income, gain or loss for federal income
      tax purposes as a result of the deposit and such defeasance and will be
      subject to federal income tax on the same amounts, in the same manner and
      at the same times as would have been the case if the deposit and such
      defeasance had not occurred.

            (5)   In the case of an election under Section 1403, the Company
      shall have delivered to the Trustee an Opinion of Counsel to the effect
      that the Holders of such Outstanding Securities and any related coupons
      will not recognize income, gain or loss for federal income tax purposes as
      a result of such covenant defeasance and will be subject to federal income
      tax on the same amounts, in the same manner and at the same times as would
      have been the case if the deposit and such covenant defeasance had not
      occurred.

                                       78

<PAGE>

            (6)   Notwithstanding any other provisions of this Section, such
      defeasance or covenant defeasance shall be effected in compliance with any
      additional or substitute terms, conditions or limitations in connection
      therewith pursuant to Section 301.

            (7)   The Company shall have delivered to the Trustee an Officer's
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for relating to either the defeasance under Section
      1402 or the covenant defeasance under Section 1403 (as the case may be)
      have been complied with.

            SECTION 1405. Deposited Money and Government Obligations to Be Held
in Trust; Other Miscellaneous Provisions. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of such Outstanding Securities and any related coupons shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Securities and any related coupons and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities
and any related coupons of all sums due and to become due thereon in respect of
principal (and premium, if any) and interest, if any, but such money need not be
segregated from other funds except to the extent required by law.

            Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(1) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 312(b) or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 1404(1) has been made in respect of such Security, or (b) a
Conversion Event occurs as contemplated in Section 312(d) or 312(e) or by the
terms of any Security in respect of which the deposit pursuant to Section
1404(1) has been made, the indebtedness represented by such Security and any
related coupons shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium, if any) and
interest, if any, on such Security as they become due out of the proceeds
yielded by converting (from time to time as specified below in the case of any
such election) the amount or other property deposited in respect of such
Security into the Currency in which such Security becomes payable as a result of
such election or Conversion Event based on the applicable Market Exchange Rate
for such Currency in effect on the third Business Day prior to each payment
date, except, with respect to a Conversion Event, for such Currency in effect
(as nearly as feasible) at the time of the Conversion Event.

            The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1404 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any related
coupons. This sentence shall survive the termination of this Indenture and the
earlier resignation or removal of the Trustee.

            Anything in this Article Fourteen to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in Section 1404 which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent defeasance or covenant defeasance, as applicable, in accordance with
this Article.

            SECTION 1406. Reinstatement. If the Trustee or any Paying Agent is
unable to apply any money in accordance with Section 1405 with respect to any
Securities by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and such Securities and any
related coupons shall be revived and reinstated as though no deposit had
occurred pursuant to Section 1402 or 1403, as the case may be, until such time
as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 1405; provided, however, that if the Company makes any
payment of principal of (or premium, if any) or interest, if any, on any such
Security or any related coupon following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Securities
and any related coupons to receive such payment from the money held by the
Trustee or Paying Agent.

                        MEETINGS OF HOLDERS OF SECURITIES

            SECTION 1501. Purposes for Which Meetings May Be Called. If

Resolution, or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1501, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of

                                       80

<PAGE>

Securities of such series in the amount above specified, as the case may be, may

to be reconvened. Notice of the reconvening of any adjourned meeting shall state
expressly the percentage, as provided above, of the principal amount of the
Outstanding Securities of such series which shall constitute a quorum.

            Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the Holders of
not less than a majority in principal amount of the Outstanding Securities of
such series; provided, however, that, except as limited by the proviso to
Section 902, any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other action which this Indenture
expressly provides may be made, given or taken by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of not less than such specified percentage in
principal amount of the Outstanding Securities of such series.

            Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of

                                       81

<PAGE>

Securities of such series and the related coupons, whether or not present or
represented at the meeting.

            Notwithstanding the foregoing provisions of this Section 1504, if
any action is to be taken at a meeting of Holders of Securities of any series
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

            (i)   there shall be no minimum quorum requirement for such meeting;
      and

            (ii)  the principal amount of the Outstanding Securities of such
      series that vote in favor of such request, demand, authorization,
      direction, notice, consent, waiver or other action shall be taken into
      account in determining whether such request, demand, authorization,
      direction, notice, consent, waiver or other action has been made, given or
      taken under this Indenture.

            SECTION 1505. Determination of Voting Rights; Conduct and
Adjournment of Meetings. (a) Notwithstanding any provisions of this Indenture,
the Trustee may make such reasonable regulations as it may deem advisable for
any meeting of Holders of Securities of a series in regard to proof of the
holding of Securities of such series and of the appointment of proxies and in
regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as its shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section 104
and the appointment of any proxy shall be proved in the manner specified in
Section 104 or by having the signature of the person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 104 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 104 or
other proof.

            (b)   The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

            (c)   At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of
Outstanding Securities of such series held or represented by him (determined as
specified in the definition of "Outstanding" in Section 101); provided, however,
that no vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairman of the meeting to be not

                                       82

<PAGE>

Outstanding. The chairman of the meeting shall have no right to vote, except as
a Holder of a Security of such series or proxy.

            (d)   Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

            SECTION 1506. Counting Votes and Recording Action of Meetings. The
vote upon any resolution submitted to any meeting of Holders of Securities of
any series shall be by written ballots on which shall be subscribed the
signatures of the Holders of Securities of such series or of their
representatives by proxy and the principal amounts and serial numbers of the
Outstanding Securities of such series held or represented by them. The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
duplicate of all votes cast at the meeting. A record, at least in duplicate, of
the proceedings of each meeting of Holders of Securities of any series shall be
prepared by the Secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was given as provided in Section 1502 and, if applicable, Section 1504.
Each copy shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one such copy shall be delivered to
the Company, and another to the Trustee to be preserved by the Trustee, the
latter to have attached thereto the ballots voted at the meeting. Any record so
signed and verified shall be conclusive evidence of the matters therein stated.

                                 ARTICLE SIXTEEN

                           SUBORDINATION OF SECURITIES

            SECTION 1601. Agreement to Subordinate. In the event a series of
Securities is designated as subordinated pursuant to Section 301 and except as
otherwise provided in a supplemental indenture or pursuant to Section 301, the
Company, for itself, its successors and assigns, covenants and agrees, and each
Holder of Securities of such series by his acceptance thereof, likewise
covenants and agrees, that the payment of the principal of (and premium, if any)
and interest, if any, on each and all of the Securities of such series is hereby
expressly subordinated, to the extent and in the manner hereinafter set forth,
in right of payment to the prior payment in full of all Senior Indebtedness.

            SECTION 1602. Distribution on Dissolution, Liquidation and
Reorganization; Subrogation of Securities. Upon any distribution of assets of
the Company upon any dissolution, winding up, liquidation or reorganization of
the Company, whether in bankruptcy, insolvency, reorganization or receivership
proceedings or upon an assignment for the benefit of creditors or any other
marshalling of the assets and liabilities of the Company or otherwise (subject
to the power of a court of competent jurisdiction to make other equitable
provision reflecting the rights conferred in this Indenture upon the Senior
Indebtedness and the holders thereof with respect to

                                       83

<PAGE>

the Securities and the holders thereof by a lawful plan of reorganization under
applicable bankruptcy law):

            (a)   the holders of all Senior Indebtedness shall be entitled to
      receive payment in full of the principal thereof (and premium, if any) and
      interest due thereon before the Holders of the Securities are entitled to
      receive any payment upon the principal (or premium, if any) or interest,
      if any, on indebtedness evidenced by the Securities; and

            (b)   any payment or distribution of assets of the Company of any
      kind or character, whether in cash, property or securities, to which the
      Holders of the Securities or the Trustee would be entitled except for the
      provisions of this Article Sixteen shall be paid by the liquidation
      trustee or agent or other person making such payment or distribution,
      whether a trustee in bankruptcy, a receiver or liquidating trustee or
      otherwise, directly to the holders of Senior Indebtedness or their
      representative or representatives or to the trustee or trustees under any
      indenture under which any instruments evidencing any of such Senior
      Indebtedness may have been issued, ratably according to the aggregate
      amounts remaining unpaid on account of the principal of (and premium, if
      any) and interest on the Senior Indebtedness held or represented by each,
      to the extent necessary to make payment in full of all Senior Indebtedness
      remaining unpaid, after giving effect to any concurrent payment or
      distribution to the holders of such Senior Indebtedness; and

            (c)   in the event that, notwithstanding the foregoing, any payment
      or distribution of assets of the Company of any kind or character, whether
      in cash, property or securities, shall be received by the Trustee or the
      Holders of the Securities before all Senior Indebtedness is paid in full,
      such payment or distribution shall be paid over, upon written notice to a
      Responsible Officer of the Trustee, to the holder of such Senior
      Indebtedness or their representative or representatives or to the trustee
      or trustees under any indenture under which any instrument evidencing any
      of such Senior Indebtedness may have been issued, ratably as aforesaid,
      for application to payment of all Senior Indebtedness remaining unpaid
      until all such Senior Indebtedness shall have been paid in full, after
      giving effect to any concurrent payment or distribution to the holders of
      such Senior Indebtedness.

            Subject to the payment in full of all Senior Indebtedness, the
Holders of the Securities shall be subrogated to the rights of the holders of
Senior Indebtedness (to the extent that distributions otherwise payable to such
Holder have been applied to the payment of Senior Indebtedness) to receive
payments or distributions of cash, property or securities of the Company
applicable to Senior Indebtedness until the principal of (and premium, if any)
and interest, if any, on the Securities shall be paid in full and no such
payments or distributions to the Holders of the Securities of cash, property or
securities otherwise distributable to the holders of Senior Indebtedness shall,
as between the Company, its creditors other than the holders of Senior
Indebtedness, and the Holders of the Securities be deemed to be a payment by the
Company to or on account of the Securities. It is understood that the provisions
of this Article Sixteen are and are intended solely for the purpose of defining
the relative rights of the Holders of the Securities, on the one hand, and the
holders of the Senior Indebtedness, on the other hand. Nothing contained in this
Article Sixteen or elsewhere in this Indenture or in the Securities is intended
to

                                       84

<PAGE>

or shall impair, as between the Company, its creditors other than the holders of
Senior Indebtedness, and the Holders of the Securities, the obligation of the
Company, which is unconditional and absolute, to pay to the Holders of the
Securities the principal of (and premium, if any) and interest, if any, on the
Securities as and when the same shall become due and payable in accordance with
their terms, or to affect the relative rights of the Holders of the Securities
and creditors of the Company other than the holders of Senior Indebtedness, nor
shall anything herein or in the Securities prevent the Trustee or the Holder of
any Security from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article Sixteen of the holders of Senior Indebtedness in respect of cash,
property or securities of the Company received upon the exercise of any such
remedy. Upon any payment or distribution of assets of the Company referred to in
this Article Sixteen, the Trustee, subject to the provisions of Section 601,
shall be entitled to rely upon a certificate of the liquidating trustee or agent
or other person making any distribution to the Trustee for the purpose of
ascertaining the Persons entitled to participate in such distribution, the
holders of Senior Indebtedness and other indebtedness of the Company, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereof
and all other facts pertinent thereto or to this Article Sixteen.

            With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or observe only such of its covenants and objectives as
are specifically set forth in this Indenture, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee, however, shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness. The
Trustee shall not be liable to any such holder if it shall pay over or
distribute to or on behalf of Holders of Securities or the Company, or any other
Person, moneys or assets to which any holder of Senior Indebtedness shall be
entitled by virtue of this Article Sixteen.

            If the Trustee or any Holder of Securities does not file a proper
claim or proof of debt in the form required in any proceeding referred to above
prior to 30 days before the expiration of the time to file such claim in such
proceeding, then the holder of any Senior Indebtedness is hereby authorized, and
has the right, to file an appropriate claim or claims for or on behalf of such
Holder of Securities.

            SECTION 1603. No Payment on Securities in Event of Default on Senior
Indebtedness. No payment by the Company on account of principal (or premium, if
any), sinking funds or interest, if any, on the Securities shall be made at
anytime if: (i) a default on Senior Indebtedness exists that permits the holders
of such Senior Indebtedness to accelerate its maturity and (ii) the default is
the subject of judicial proceedings or the Company has received notice of such
default. The Company may resume payments on the Securities when full payment of
amounts then due for principal (premium, if any), sinking funds and interest on
Senior Indebtedness has been made or duly provided for in money or money's
worth.

            SECTION 1604. Payments on Securities Permitted. Nothing contained in
this Indenture or in any of the Securities shall (a) affect the obligation of
the Company to make, or prevent the Company from making, at any time except as
provided in Sections 1602 and 1603, payments of principal of (or premium, if
any) or interest, if any, on the Securities or (b) prevent the application by
the Trustee of any moneys or assets deposited with it hereunder to the

                                       85

<PAGE>

payment of or on account of the principal of (or premium, if any) or interest,
if any, on the Securities, unless a Responsible Officer of the Trustee shall
have received at its Corporate Trust Office written notice of any fact
prohibiting the making of such payment from the Company or from the holder of
any Senior Indebtedness or from the trustee for any such holder, together with
proof satisfactory to the Trustee of such holding of Senior Indebtedness or of
the authority of such trustee more than two Business Days prior to the date
fixed for such payment.

            SECTION 1605. Authorization of Holders to Trustee to Effect
Subordination. Each Holder of Securities by his acceptance thereof authorizes
and direct the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article Sixteen
and appoints the Trustee his attorney-in-fact for any and all such purposes.

            SECTION 1606. Notices to Trustee. Notwithstanding the provisions of
this Article or any other provisions of this Indenture, neither the Trustee nor
any Paying Agent (other than the Company) shall be charged with knowledge of the
existence of any Senior Indebtedness or of any fact which would prohibit the
making of any payment of moneys or assets to or by the Trustee or such Paying
Agent, unless and until a Responsible Officer of the Trustee or such Paying
Agent shall have received (in the case of a Responsible Officer of the Trustee,
at the Corporate Trust Office of the Trustee) written notice thereof from the
Company or from the holder of any Senior Indebtedness or from the trustee for
any such holder, together with proof satisfactory to the Trustee of such holding
of Senior Indebtedness or of the authority of such trustee and, prior to the
receipt of any such written notice, the Trustee shall be entitled in all
respects conclusively to presume that no such facts exist; provided, however,
that if at least two Business Days prior to the date upon which by the terms
hereof any such moneys or assets may become payable for any purpose (including,
without limitation, the payment of either the principal (or premium, if any) or
interest, if any, on any Security) a Responsible Officer of the Trustee shall
not have received with respect to such moneys or assets the notice provided for
in this Section 1606, then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
moneys or assets and to apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary which may be
received by it within two Business Days prior to such date. The Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee on
behalf of such holder) to establish that such a notice has been given by a
holder of Senior Indebtedness or a trustee on behalf of any such holder. In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article Sixteen, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article Sixteen and, if such evidence is not furnished,
the Trustee may defer any payment to such Person pending judicial determination
as to the right of such Person to receive such payment.

            SECTION 1607. Trustee as Holder of Senior Indebtedness.

                                       86

<PAGE>

            The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article Sixteen in respect of any Senior Indebtedness
at any time held by it to the same extent as any other holder of Senior
Indebtedness and nothing in Section 613 or elsewhere in this Indenture shall be
construed to deprive the Trustee of any of its rights as such holder. Nothing in
this Article Sixteen shall apply to claims of, or payments to, the Trustee under
or pursuant to Sections 506 or 606.

            SECTION 1608. Modifications of Terms of Senior Indebtedness. Any
renewal or extension of the time of payment of any Senior Indebtedness or the
exercise by the holders of Senior Indebtedness of any of their rights under any
instrument creating or evidencing Senior Indebtedness, including, without
limitation, the waiver of default thereunder, may be made or done all without
notice to or assent from the Holders of the Securities or the Trustee. No
compromise, alteration, amendment, modification, extension, renewal or other
change of, or waiver, consent or other action in respect of, any liability or
obligation under or in respect of, or of any of the terms, covenants or
conditions of any indenture or other instrument under which any Senior
Indebtedness is outstanding or of such Senior Indebtedness, whether or not such
release is in accordance with the provisions of any applicable document, shall
in any way alter or affect any of the provisions of this Article Sixteen or of
the Securities relating to the subordination thereof.

            SECTION 1609. Reliance on Judicial Order or Certificate of
Liquidating Agent. Upon any payment or distribution of assets of the Company
referred to in this Article Sixteen, the Trustee and the Holders of the
Securities shall be entitled to rely upon any order or decree entered by any
court of competent jurisdiction in which such insolvency, bankruptcy,
receivership, liquidation, reorganization, dissolution, winding up or similar

forth below, the above-captioned Securities held by you for our account (i) are
owned by person(s) that are not citizens or residents of the United States,
domestic partnerships, domestic corporations or any estate or trust the income
of which is subject to United States federal income taxation regardless of its
source ("United States person(s)"), (ii) are owned by United States person(s)
that are (a) foreign branches of United States financial institutions (financial
institutions, as defined in United States Treasury Regulations Section
2.165-12(c)(1)(v) are herein referred to as "financial institutions") purchasing
for their own account or for resale, or (b) United States person(s) who acquired
the Securities through foreign branches of United States financial institutions
and who hold the Securities through such United States financial institutions on
the date hereof (and in either case (a) or (b), each such United States
financial institution hereby agrees, on its own behalf or through its agent,
that you may advise [Name of Issuer] or its agent that such financial
institution will comply with the requirements of Section 165(j)(3)(A), (B) or
(C) of the United States Internal Revenue Code of 1986, as amended, and the

and, in addition, if the owner is a United States or foreign financial
institution described in clause (iii) above (whether or not also described in
clause (i) or (ii)), this is to further certify that such financial institution
has not acquired the Securities for purposes of resale directly or indirectly to
a United States person or to a person within the United States or its
possessions.

            As used herein, "United States" means the United States of America
(including the states and the District of Columbia); and its "possessions"
include Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, Wake Island
and the Northern Mariana Islands.

            We undertake to advise you promptly by tested telex on or prior to
